Checked in.

Dump of assembler code for function main:
.../gdb/testsuite/gdb.arch/i386-signal.c:
30 {
0x000000000040057f <+0>: push %rbp
0x0000000000400580 <+1>: mov %rsp,%rbp

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.
