Add a new form of USE_GCC, USE_GCC=yes, which generically requests
a current version of GCC. This reduces churn for individual ports
and further increases consistency (in line with a canonical version
that we introduced with GCC_DEFAULT_VERSION earlier on and the older
USE_FORTRAN=yes).
On the way, make some comments more consistent.
