The path we pass to rustc will be visible in panic messages and
backtraces: they will be user visible!
Avoid junk in these paths by passing relative paths to rustc.
For most advanced users, `libcore` or `libstd` in the path will be
a clue to the location -- inside our code, not theirs.
Store both the relative path to the source as well as the absolute.
Use the relative path where it matters, compiling the main crates,
instead of changing all of the build process to cope with relative
paths.
Example output after this patch:

# Rust's standard distribution of crates and tools
|
|
#
|
|
# The crates outlined below are the standard distribution of libraries provided
|
|
# in a rust installation. These rules are meant to abstract over the
|
|
# dependencies (both native and rust) of crates and basically generate all the
|
|
# necessary makefile rules necessary to build everything.
|
|
#
|
|
# Here's an explanation of the variables below
|
|
#
|
|
# TARGET_CRATES
|
|
# This list of crates will be built for all targets, including
|
|
# cross-compiled targets
|
|
#
|
|
# HOST_CRATES
|
|
# This list of crates will be compiled for only host targets. Note that
|
|
# this set is explicitly *not* a subset of TARGET_CRATES, but rather it is
|
|
# a disjoint set. Nothing in the TARGET_CRATES set can depend on crates in
|
|
# the HOST_CRATES set, but the HOST_CRATES set can depend on target
|
|
# crates.
|
|
#
|
|
# TOOLS
|
|
# A list of all tools which will be built as part of the compilation
|
|
# process. It is currently assumed that most tools are built through
|
|
# src/driver/driver.rs with a particular configuration (there's a
|
|
# corresponding library providing the implementation)
|
|
#
|
|
# DEPS_<crate>
|
|
# These lists are the dependencies of the <crate> that is to be built.
|
|
# Rust dependencies are listed bare (i.e. std) and native
|
|
# dependencies have a "native:" prefix (i.e. native:hoedown). All deps
|
|
# will be built before the crate itself is built.
|
|
#
|
|
# TOOL_DEPS_<tool>/TOOL_SOURCE_<tool>
|
|
# Similar to the DEPS variable, this is the library crate dependencies
|
|
# list for tool as well as the source file for the specified tool
|
|
#
|
|
# You shouldn't need to modify much other than these variables. Crates are
|
|
# automatically generated for all stage/host/target combinations.
