[RFA/RFC] testsuite: gdb_run_cmd tweak

This just adds a regular expression to prevent gdb_run_cmd
from choking on the msg that gdb emits when it detects that
the file has changed and re-reads the symbols.

I honestly don't remember the circumstances that caused me
to add this -- it's been sitting in my sandbox for a while.
Thought it would be better to offer it up than to throw it
away...

	* lib/gdb.exp (gdb_run_cmd): Keep going past "executable has 
	changed" msg.
