Instead of using "-L/path/to -llib" use "/path/to/lib.a".

I suggest you test this independently, I would expect that
your binaries will not pass the "test" even with --enable-pic:
You may have to use --disable-asm (which of course makes
your resulting binaries nearly unusable), the same is likely
true for x264 (where the effect is probably even worse).
