[rfc/testsuite] i386-sse.exp: better output if no SSE support

[mec.gnu@mindspring.com (Michael Elizabeth Chastain)]

This patch fixes i386-sse.exp for compilers that don't support SSE,
specifically gcc 2.95.3.  Before this patch, the results are:

   3 ERROR
   2 WARNING
  33 FAIL
   1 UNRESOLVED

After this patch, the results are a single UNSUPPORTED.
My view is that people should be reading all their non-PASS results,
including the UNRESOLVED, UNSUPPORTED, and UNTESTED results.
We might want to discuss this.

I tested this on native i686-pc-linux-gnu, gcc 2.95.3 and 3.3.3,
dwarf-2 and stabs+.  My processor has SSE (Intel Celeron).

I'm giving this 48 hours for comment and then committing it.

	Fix PR testsuite/1679.
	* gdb.arch/i386-sse.exp: Do not call gdb_suppress_entire file.
	Issue an UNSUPPORTED result instead.
