Instead, #include config.h at the top of common.h so that av_always_inline
does not get doubly defined.

Not all compilers claiming to be gcc support this attribute.

It is possible that the compiler requires flags set by the --cpu
option, so we should not attempt to run it before those flags have
been added.

We do not issue similar warnings for other architectures, and we
generally assume users know what they want.

builds.

If the adventurous want it back, they can edit the makefile themselves.

Altivec, NEON, and SSE require more alignment than standard malloc()
