mk/compiler.mk is included after mk/bsd.hacks.mk in mk/bsd.pkg.mk,
so it must be included in hacks.mk exactly before using CC_VERSION.
Don't override gcc variables, use ones specific to gcc-libs.

Avoids issue with USE_PKGSRC_GCC_RUNTIME where the gcc48 package would
end up installing to gcc47's prefix.
Add USE_PKGSRC_GCC_RUNTIME support for gcc 4.8 and fix dependencies for
gcc packages.  Bail out if runtime support is requested but we do not
provide runtime libraries for the chosen compiler.

Bump PKGREVISION since this changes an installed header file.
