A few tests on the testsuite require dwarf5 to work. Up until now, the way to do this was to explicitly add the command line flag -gdwarf-5. This isn't very portable, in case a compiler requires a different flag to emit dwarf5. This commit adds a new option to gdb_compile that would be able to add the correct flag (if known) or error out in case we are unable to tell which flag to use. It also changes the existing tests to use this general option instead of hard coding -gdwarf-5. Reviewed-by: Keith Seitz <keiths@redhat.com> Approved-By: Tom Tromey <tom@tromey.com>
