[RFC] delete gdb.cp/ambiguous.exp ?

[Doug Evans <dje at google dot com>]

Along the lines of dead code removal ...

What should we do with this testcase?

The messages it is looking for from gdb do not exist,
but the whole thing is not run for gcc anyway.

I ask because if we choose to not delete the testcase
then I will need to add a similar escape for clang.
