testsuite: handle SIGLOST/SIGPWR conflict in sparc64-*-linux-gnu targets.

2013-10-03  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* gdb.base/sigall.exp (test_one_sig): gdb identifies SIGLOST as a
	SIGPWR in sparc64.

	* gdb.base/sigall.c (main): In some targets SIGLOST and SIGPWR
	have the same signal number.  Handle this situation.
