description:
If the base GCC isn't enough, and GCC_REQD=4.5 to 6, use gcc6.

gcc4.8,4.9,5 have bugs preventing them from being useful within pkgsrc
for the primary use case that finds them handy:
glibc + FORTIFY + those GCC versions = build failures.

Additionally, requiring fewer versions of GCC is an improvement for
the vast majority of use-cases considered.

We might want to bump this further than gcc6 later on, but this is a
big improvement for CentOS builds.
