[committed][gdb/testsuite] Fix gdb.base/break-interp.exp for ld.so without debug

[Tom de Vries via Gdb-patches <gdb-patches@sourceware.org>]

Hi,

When running test-case gdb.base/break-interp.exp on openSUSE Leap 42.3, I get:
...
(gdb) info addr dl_main^M
Symbol "dl_main" is at 0x1750 in a file compiled without debugging.^M
(gdb) FAIL: gdb.base/break-interp.exp: info addr dl_main
...
while the regexp expects "Symbol \"dl_main\" is a function at address $hex\\."

Fix this by also accepting this variant.

Tested on x86_64-linux.

Committed to trunk.

Thanks,
- Tom
