[x264-devel] [PATCH] Do not play with cflags on AArch64

[Marcin Juszkiewicz]

x264 has AArch64 support. But I had to remove some lines from it's
configure script to make it build.

All because it tries to be too smart. Sure, there is no need to check
for NEON as on this architecture it is mandatory. But I left code for 
it alone. But there is no such switch in gcc as "-arch" one so let's
kill line which tries to add it.
