    gdb.trace: Fix unavailable.exp if last register happens to be PC.
    
    unavailable.exp executes "info registers", expecting to find at least
    two instances of "<unavailable>".  However, it uses
    "<unavailable>.*<unavailable>" as the pattern, which doesn't match
    when the last register happens to be available (eg. PC).  Change it
    to ".*<unavailable>.*<unavailable>.*" instead.
    
    Noticed on s390, no regression on x86_64.
    
    gdb/testsuite/ChangeLog:
    
    	* gdb.trace/unavailable.exp (gdb_unavailable_registers_test_1): Fix
    	info registers pattern.
