multimedia/x264 - use base compiler on PowerPC64/ELFv2

[alfredo]

Summary

Environment running PowerPC64 with the ELFv2 uses llvm9 as base compiler, so we can remove GCC dependency.

[pkubaj]

powerpc and powerpcspe also switch to LLVM, so we should change default options there as well.

[alfredo]

check compiler type

[alfredo]

remove explicit GCC dependency and add "modern compiler dependency" instead (compiler:c11)

[pkubaj]

Now it's not necessary to put include bsd.port.pre.mk and bsd.port.post.mk separately.

[pkubaj]

Also, PGO options seems to require GCC. Why do you remove USE_GCC=any there? Have you verified it's not needed?

I'll revert this part to keep safe, affects behavior on platforms other than powerpc*

[alfredo]

reverted PGO part

No problem, could you then resign from being a reviewer here?

[pkubaj]

Still includes unnecessarily bsd.port.pre.mk. but I will fix it in the commit.
