The Objective C port in lang/objc has the same problem. The Makefile
detects if there is an Objective C compiler and if not, it downloads
a bootstrap version of the compiler as C source and builds that first.
It then uses the bootstrap compiler to build the Objective C compiler
and support libraries. This way, you don't have to add a
"make bootstrap" step.
