[PATCH] Fix a SPARC -mcbcond compare-and-branch out of range failure.

OK for all active branches, but the ChangeLog entry should be something like:

	* config/sparc/sparc.md (length): Return the correct value for -mflat
	sibcalls to match output_sibcall.

Note that we *never* use a pair of parentheses after function names.
