sparc: Define FFI_TARGET_SPECIFIC_VARIADIC for v9

Browse Source 
This is a port of

  http://gcc.gnu.org/viewcvs?rev=207763&root=gcc&view=rev

aka GCC PR libffi/60073, to the rewritten Sparc codebase.
Supposedly, we should have seen failures with the existing
libffi.call/cls_double_va.c testcase, but I hadn't.
Perhaps a gcc newer than 4.6.3 is required to see that...
