Debian wants to build all binaries with particular hardening flags.
The Rust makefiles are inconsistent in which architectures they
correctly include CFLAGS/etc from the enivoronment (see mk/cfg/*).
This patch adds LDFLAGS, and then unconditionally prepends
CFLAGS/LDFLAGS/etc to the build commands.
The book was located under 'src/doc/trpl' because originally, it was
going to be hosted under that URL. Late in the game, before 1.0, we
decided that /book was a better one, so we changed the output, but
not the input. This causes confusion for no good reason. So we'll change
the source directory to look like the output directory, like for every
other thing in src/doc.
Rather than modifying the installer to disable directory rewriting,
this patch modifies the directory structure passed to the installer so
that the rewriting gives the correct results. This means that if a
non-standard --libdir is passed to configure then the same --libdir
option (relative to the --prefix) must be passed to the install
script. In the `make install` case this is handled automatically.
Binary distributions are generally generated using the default
--libdir and then have paths optionally rewritten by the installer,
which should continue to work.
This has the advantage of not complicating the installer interface
intended for end-user use.
Fixes#29561
On distros that use i486 or i586 in their CHOST, Rust will fail to build
because it is not handling i486 or i586 like i686 is handled. This
changes the match to do work for all instances of i?86 instead of just
i686. The Yocto Project still uses i586 as a target.

under openbsd, the library path of libstdc++ need to be explicit (due
to the fact the default linker `cc` is gcc-4.2, and not gcc-4.9).
but when a recent LLVM is installed, rustc compilation pikes the bad
LLVM version (which live in /usr/local/lib, which is same directory of
libestdc++.so for gcc-4.9).
this patch move the libstdc++ path from RUST_FLAGS_<target> to special
variable, and use it *after* LLVM_LIBDIR_RUSTFLAGS_<target> in
arguments.

I noticed the nomicon was not listed!
I also removed links to racer and rustfmt since they were not *doc-specific* links, just links to tools, as well as pointed the cargo link directly at the docs.
Removed all the community stuff. There are lots of other places to find this now, including the website.
With pending website changes this page will continue to be pared back, reflecting only what's in-tree, not general Rust docs.

This should get `--libdir` working as well as it was a couple of weeks ago. (That is, it still rewrites paths incorrectly but it no longer fails during `make install`.)
Fixesgentoo/gentoo-rust#28 and gentoo/gentoo-rust#29.
This is to handle the case where CFG_LIBDIR is not a direct child of
CFG_PREFIX (in other words, where CFG_LIBDIR_RELATIVE has more than
one component).
Emacs warns that makefile lines that start with spaces followed by
tabs are "suspicious". These were harmless since they were
continuation lines, but getting rid of the warning is nice and this
version looks better.
The important one is $(MAKE). make handles recipes containing the
literal string "$(MAKE)" specially, so it is important to make sure it
isn't evaluated until recipe invocation time.

Quite a bit of cruft in the valgrind suppressions. I started from a clean slate and found a few unique failures; this commit also moves the tests "fixed" by these suppressions into run-pass-valgrind.
* Delete `sys::unix::{c, sync}` as these are now all folded into libc itself
* Update all references to use `libc` as a result.
* Update all references to the new flat namespace.
* Moves all windows bindings into sys::c
According to a recent [discussion on IRC](https://botbot.me/mozilla/rust-tools/2015-10-27/?msg=52887517&page=2), there's no good reason for Windows builds to store target libraries under `bin`, when on every other platform they are under `lib`.
This might be a [breaking-change] for some users. I am pretty sure VisualRust has that path hard-coded somewhere.

Note: for now, this change only affects `-windows-gnu` builds.
So why was this `libgcc` dylib dependency needed in the first place?
The stack unwinder needs to know about locations of unwind tables of all the modules loaded in the current process. The easiest portable way of achieving this is to have each module register itself with the unwinder when loaded into the process. All modules compiled by GCC do this by calling the __register_frame_info() in their startup code (that's `crtbegin.o` and `crtend.o`, which are automatically linked into any gcc output).
Another important piece is that there should be only one copy of the unwinder (and thus unwind tables registry) in the process. This pretty much means that the unwinder must be in a shared library (unless everything is statically linked).
Now, Rust compiler tries very hard to make sure that any given Rust crate appears in the final output just once. So if we link the unwinder statically to one of Rust's crates, everything should be fine.
Unfortunately, GCC startup objects are built under assumption that `libgcc` is the one true place for the unwind info registry, so I couldn't find any better way than to replace them. So out go `crtbegin`/`crtend`, in come `rsbegin`/`rsend`!
A side benefit of this change is that rustc is now more in control of the command line that goes to the linker, so we could stop using `gcc` as the linker driver and just invoke `ld` directly.
It looks like the target libs aren't actually the same across hosts so instead
of always packaging the target libs from CFG_BUILD take the target libs from the
host if we have them and then only failing that do we take them from CFG_BUILD.
Closes#29228
