Log:

gcc/
	* config/rs6000/rs6000.c (rs6000_output_function_epilogue):
	Add check for UPC when defining the language type value
	in a traceback entry.

gcc/upc/
	* config-lang.in: Remove checks for supported targets.
	This is now done at a higher level.

libgupc/
	* smp/upc_sync.h (GUPCR_WRITE_FENCE, GUPCR_READ_FENCE):
	For powerpc, also check __PPC__ pre-processor definition,
	as 'PPC' is apparently not defined on 64-bit PPC targets.
	* smp/upc_sysdep.c (__upc_atomic_cas): Implement as external
	procedure only if builtin compare-and-swap is unavailable.
	* smp/upc_sysdep.h (__upc_atomic_cas): Ditto.
