re PR target/9316 (powerpc-rtems/extending multilibs)

2003-01-30	Ralf Corsepius <corsepiu@faw.uni-ulm.de>

	PR target/9316
	* config/rs6000/rtems.h: Add CPP_OS_DEFAULT_SPEC.
	* config/rs6000/sysv4.h: Add CPP_OS_RTEMS_SPEC.
	* config/rs6000/t-rtems: New file. multilib variants to match OS.
	* config.gcc (powerpc-*-rtems*): Use rs6000/t-rtems instead of
	rs6000/t-ppcgas so we get the desired multilibs.

From-SVN: r62139
