This is that patch. I figured out how to run x32 binaries on my
system. With this patch, everything passes except some code using
getpwuid_r, which also fails in plain C so I'm not going to worry
about it. That said, I do not see some of the failures you mentioned.
In any case, this patch does pass bootstrap and testing on
x86_64-pc-linux-gnu both with and without -mx32. Committed to
mainline.
