The c-c++-common tests fail (or XPASS depending on which) on
powerpc Darwin because it doesn't currently emit .ident marker.

Since there's no support for .ident in the assembler, we can't
enable the output and therefore these tests should be skipped.

darwin, configuration, check properly for dwarf2 debug line support

This corrects a long-standing misconfiguration for Darwin.
The assembler supports the “.file” and “.loc” directives, but
the GCC configury was not detecting this because it was
using objdump, which does not exist on most Darwin installations.

We added support for “otool” to GCC and now we can use that to
make the check that’s done with objdump on ELF targets.
