Patch to switch "--enable-64-bit-words" on

Flac-1.3.2 has a configure switch to enable 8 bytes words on 64bit systems, but it's disable by default. See this git commit:
https://git.xiph.org/?p=flac.git;a=commit;h=6cc1cbad2c40a4406fd911445b86b3df2291dd79

Working on 8 bytes at times give some performance (5%-10% IIRC) improvement, so it would be nice to have it enabled in the ebuild.
I've added a check for CHOST=x86_64 to the flac-1.3.2-r1 ebuild, and it works on my system, but i'm no expert on ebuild writing.
