Previously this function used channels but this isn't necessary any more now
that threads have return values. This also has the added bonus of appropriately
waiting for the thread to exit to ensure that the function doesn't still have
running threads once it returns.
the const evaluator has a bool constant value, no need to use integers
the `fromb` function is very old. It took me a while of git-blame until i found where it was created. I think it was just a hack. All tests still pass.
I also forbade `&&` and `||` on integral types

I'm not sure if those renames are ok. [TokenType::Tt* to TokenType::*](https://github.com/rust-lang/rust/pull/29582) was obvious, but for all those Item-enums it's less obvious to me what the right way forward is due to the underscore.
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.

While these points are true, we're not going for 100% accuracy here,
this is introductory material. Changing these things would be more
confusing, but it is important to note that we're presenting an
abstraction here.

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.

Otherwise, the iterator and the functions for getting specific
environment variables might disagree, for environments like
FOOBAR
Variable names starting with equals sign are OK:
glibc only interprets equals signs not in the first position as
separators between variable name and variable value. Instead of skipping
them entirely, a leading equals sign is interpreted to be part of the
variable name.
