Define rustc's host triple at compile time This way a cross-compiled rustc's answer to host_triple() is correct. The return value of host_triple() reflects the actual host triple that the compiler was build for, not the triple the compiler is being built on

Refactor the build system for easily adding crates Before this patch, if you wanted to add a crate to the build system you had to change about 100 lines across 8 separate makefiles. This is highly error prone and opaque to all but a few. This refactoring is targeted at consolidating this effort so adding a new crate adds one line in one file in a way that everyone can understand it.

# RUST_TARGET_STAGE_N template: This defines how target artifacts are built
# for all stage/target architecture combinations. This is one giant rule which
# works as follows:
#
# 1. The immediate dependencies are the rust source files
# 2. Each rust crate dependency is listed (based on their stamp files),
# as well as all native dependencies (listed in RT_OUTPUT_DIR)
# 3. The stage (n-1) compiler is required through the TSREQ dependency, along
# with the morestack library
# 4. When actually executing the rule, the first thing we do is to clean out
# old libs and rlibs via the REMOVE_ALL_OLD_GLOB_MATCHES macro
# 5. Finally, we get around to building the actual crate. It's just one
# "small" invocation of the previous stage rustc. We use -L to
# RT_OUTPUT_DIR so all the native dependencies are picked up.
# Additionally, we pass in the llvm dir so rustc can link against it.
# 6. Some cleanup is done (listing what was just built) if verbose is turned
# on.

Lots of build system cleanup and documentation This splits mk/stageN.mk into host.mk and target.mk and makes the build rules somewhat simpler - there's no more building from stageN into stageN+1; instead we always build from stageN(host) to stageN(target) then promote from stageN(target) to stageN+1(host). Add a big honkin explaination right at the top of Makefile.in

Make build products depend on their target directories. This is an attempt to address Issue #3326 by adding [*order-only*][1] prerequsites of each build product on the directory where it is to go. It is important that the prerequisites be order-only, since the timestamp on a parent directory is not relevant to whether a product is out of date; the parent directory merely needs to exist.
