fix darwin boostrap breakage

RIght now darwin doesn't build for me (something for goolge to find):

Undefined symbols:
  "LPR2", referenced from:
      ___mulsc3 in _mulsc3_s.o
      ___muldc3 in _muldc3_s.o
      ___mulxc3 in _mulxc3_s.o


I think it is due to a updated macports bit that I've not tracked down.  :-(

I've not seen the build failure this fixes, but others have, so I'm applying it.  I've built cc1, which is the most I can do right now.

	* config/darwin-protos.h (machopic_select_rtx_section): Move to
	inside RTX_CODE ifdef.

You didn't do anything nutty like install binutils ;)?

Found it, rm -rf `find . -name  autom4te.cache` in the source tree solves it.  :-(  You know, rm -rf the build is obvious and anyone can do that, by rm -rf the source tree is, well, anti-solcial.
