ports-gcc does error out on implicit-int errors. hplip has one of those
and the fix is trivial.

On top of this it seems that -hpcups does not need ${COMPILER_LIBCXX} at
least this cause some strange issues on my sparc64 build box. Now that
part I'm not sure about so someone understanding this should double check.
