	https://savannah.gnu.org/bugs/?22081
	support sparc64 for solaris & *bsd
	* avcall/avcall-sparc64.c, avcall/avcall.h.in:
	Kill callee (%g2). Sparc64 doesn't need that code.
	Delete space[] - gcc optimizes it away anyway, and it doesn't
	guarantee correct operation even if it's not removed - if compiler
	allocs it below other local vars on the stack, then calling
	function with enough arguments will clobber local vars.
	Instead i've changed the code to use alloca, see the comment in
	the code for details on why this works. It also doesn't waste 2K
	of stack on each call, we only grab the space we actually need.
	I nuked farg_mask. It's not necessary for float args, marking
	them in darg_mask does the right thing (new av_float). And they
	just hurt structure passing, where, again, marking up darg_mask
	does the right thing.
	* avcall/avcall-saprc64.S: Regenerated with NetBSD gcc4
	* vacall/vacall-sparc64.S, callback/vacall_r/vacall-sparc64.S:
	New binutils on sparc64 insist on having global registers properly
	declared with .register. I've just added the declarations manually
	w/out actually regenerating the files to demonstrate that's the
	only change needed there. IF the files are regenerated with a
	newer compiler you will get them automatically.
