[Message part 1 (text/plain, inline)]

I'm trying to see if the rust bootstrap process works on core-updates
and I was unable to build for i686-linux on x86_64 linux. I failed to
build xz, due to some assembly optimizations. It turns out that instead
of using i686 binaries it was using x86_64 binaries and targeting i686,
while passing flags saying it was i686.

It seems there are some other things which need another look. From the
PATH variable:

The ones listed in the environmental file at the base of the build
listed x86_64 binaries.

That’s embarrassing.  I think this was fixed by
98c075c24e26798ef52ab66641faa7b0aa87726b.

Let me know if anything’s amiss!
