Upstream build scripts have some machinery to include compiler-specific
.mak file depending on compiler used. This is handled in an ugly way by the
port, roughly, upstream makefile includes ${CC}.mak and ports Makefile
copies that from default .mak. This is breaks when CC is an absolute path
and is useless anyway, as even if it was implemented properly, customized
.mak files are for compilers we'll never use such as gcc 3.2, intel and suncc.
So make upstream makefile always include the default .mak.
