Well after tracing through several Makefiles I pinned down the variable
needed to compiler 64-bit capable gcc:
setting the above in /usr/pkg/etc/mk.conf and building gcc in pkgsrc,
will produce a C compiler which by default generates 64-bit code, and
has support for generating 32-bit code with -m32 flag.
