Hi,

The c-c++-common tests fail (or XPASS depending on which) on Darwin
because it doesn't currently emit .ident marker.  For X86 Darwin, this
is a trivial oversight; the assembler supports the directive.  We can
therefore use the default target hook there.

I applied the following as obvious,

Iain
