	pkgsrc/lang/gcc: buildlink2.mk

Log Message:
Create a buildlink2.mk file for lang/gcc.  Aside from the usual tunable
variables, there is a new one, GCC_REQD, that contains the minimum version
of GCC needed to compile the package.  For the purpose of version
comparison, all versions of EGCS are considered to be gcc-2.8.1.

This buildlink2.mk file attempts to be smart, so if the gcc in your path is
actually the one from lang/gcc, then it's considered that you need lang/gcc
at least at build-time.

There is also a new variable USE_CXX, that tells the buildlink2.mk file
whether you need to link against libstdc++.so, and thus need a _full_
dependency on lang/gcc.
