auto merge of #20980 : richo/rust/final-power, r=alexcrichton

Browse Source 
Originally, this was going to be discussed and revisted, however I've been working on this for months, and a rebase on top of master was about 1 flight's worth of work so I just went ahead and did it.

This gets you as far as being able to target powerpc with, eg:

    LD_LIBRARY_PATH=./x86_64-unknown-linux-gnu/stage2/lib/ x86_64-unknown-linux-gnu/stage2/bin/rustc -C linker=powerpc-linux-gnu-gcc --target powerpc-unknown-linux-gnu hello.rs

Would really love to get this out before 1.0. r? @alexcrichton
