bug with -mflat on UltraSparc I

[Jim Wilson]

The addition of the SPARC V9 support accidentally broke the -mflat support.
I installed the following patch to fix this testcase.  -mflat support isn't
tested very often, so it is possible that there are other problems too.

	* sparc.h (SPARC_INCOMING_INT_ARG_FIRST): Support TARGET_FLAT.
