[PATCH] testsuite: sigall.exp: handle SIGLOST/SIGPWR conflict in sparc64 targets

[Jose E. Marchesi]

    Hi.
    
    In sparc64 SIGLOST and SIGPWR have the same signal number.  The
    following patch fixes gdb.base/sigall.exp accordingly.
    
    Tested in sparc64-unknown-linux-gnu.
    
    2013-10-23  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.
