    testsuite: Fix recent GCC FAIL: gdb.arch/i386-signal.exp
    
    gcc-6.2.1-2.fc24.x86_64
    
    (gdb) backtrace 10^M
    (gdb) FAIL: gdb.arch/i386-signal.exp: backtrace 10
    
    (gdb) disas/s
    Dump of assembler code for function main:
    .../gdb/testsuite/gdb.arch/i386-signal.c:
    30      {
       0x000000000040057f <+0>:     push   %rbp
       0x0000000000400580 <+1>:     mov    %rsp,%rbp
    31        setup ();
       0x0000000000400583 <+4>:     callq  0x400590 <setup>
    => 0x0000000000400588 <+9>:     mov    $0x0,%eax
    32      }
       0x000000000040058d <+14>:    pop    %rbp
       0x000000000040058e <+15>:    retq
    End of assembler dump.
    
    The .exp patch is an obvious typo fix I think.  The regex was written to
    accept "ADDR in main" and I find it OK as checking .debug_line validity is not
    the purpose of this testfile.
    
    gcc-4.8.5-11.el7.x86_64 did not put the 'mov $0x0,%eax' instruction there at
    all so there was no problem with .debug_line.
