[PATCH] Don't run ident tests on powerpc-darwin

[Iain Sandoe <iain at sandoe dot co dot uk>]

Hi

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

For powerpc darwin (and, I think, AIX - hence copying David), there’s no
.ident support in the assembler, and we need to skip the tests.

In this case, I suggest that it’s not worth having a target-supports entry.
This is because what a target chooses to emit for -fident is controlled by
a target hook and therefore there’s no guarantee that a target-supports
that triggers off “ .ident” in the asm would be generically useful.

OTOH, if the testsuite maintainers prefer a support .. it can be done ;-)

OK for trunk?
Iain
