handbrake != mencoder ;)

You should only use --enable-x264 when absolutely needed and you're
sure you meet all the requirements. Recommended is to not explicitly
use args in configure and let the configure detect stuff by itself. If
it can't, it can mean four things

1. there's a bug in configure
2. your system is missing something thus it skips it
3. you have it, but it's too old so configure skips it
4. configure can't detect it as it's in a non-standard path (rarely happens)

Yes, probably the latest from x264 git
