Split the gasnet target in the third-party Makefile
into two distinct targets: gasnet-config and gasnet-build.
Typical users should still use "make" or "make all" or
"make gasnet" in this directory to make gasnet.  Those
working on modifying gasnet code itself may want to use
"make gasnet-build" in order to avoid redundant
gasnet-config steps.
