Subject: [PATCH] Fix X32 build by disabling asm
This applies gentoo's x32 patch, adjusted slightly, which disables asm support
for x32 as well as correcting -m.
Debian has a different patch which does the same, and there's a superior yet
out of date patch series on the x264 list which keeps asm support enabled, but
doesn't successfully build at this time, and my assembly is very rusty.
