This made bluray to work

I don't know how, but I ended up with instead of the last revision.
And it work O_o

I think the bluray problem was related to the "export BLURAY_LIBS='-lbluray -lfreetype -lexpat -lz -lbz2'".
Update cross_compile_ffmpeg.sh
Merge pull request #44 from gcsx/patch-2

Tested bluray by mistake and it works!
