Subject: x264: for x32, disable asm and pass -mx32

We should probably patch it to stop adding the -m argument to CFLAGS/LDFLAGS
in the first place, since we pass it in via CC, but this will do for now.

+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+out of date patch series on the x264 list which keeps asm support enabled, but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.
