Trying to build a minimal set of rust libraries to link against for cross compiling to a 32 bit host.

./configure --enable-rustbuild --target=i686-unknown-linux-gnu
python src/bootstrap/bootstrap.py --stage 0 --step libstd --target i686-unknown-linux-gnu

Things look okay until trying to build compiler-rt

@JustAPerson this may have been fixed by #34578, could you check to see whether or not you're checkout has that commit yet?

@alexcrichton reporter claimed to have had cloned a fresh rust repository yesterday, so the PR must have been in.

Oh looking again it appears that you're building with rustbuild which I believe hasn't been fixed in this regard.

@JustAPerson if you compile with CFLAGS_i686_unknown_linux_gnu=-march=i686 does it work for you?
