AFAICT, this should be fixed now.

warn that -fobjc-gc is ignored for -fgnu-runtime and set flag_objc_gc to 0

a warning seems enough here .. although error-out would be possible.

NOTE; there's no reason to skip this the tests on linux - I've taken out the
*-*-darwin and confirmed that the tests pass on ia32-pc-linux

The GNU runtime does not need help from the compiler to do the job. 

-fobjc-gc should error out if used with the GNU runtime at compile time.

I'm not sure that's the case, as I've taken a look at the gcc libobjc code, and
it does seem to have some support for boehm GC integration. For example, a
fragment of code from gcc-4.2.3/libobjc/objects.c runs as follows:

#if OBJC_WITH_GC
  if (CLS_ISCLASS (class))
new = (id) GC_malloc_explicitly_typed (class-instance_size,
   class-gc_object_type);
#else
  if (CLS_ISCLASS (class))
new = (*_objc_object_alloc) (class);
#endif

Of course, perhaps that's just preliminary code for support in some future
version, and the vanilla gcc runtime doesn't support --enable-objc-gc. But if
that's so, there's still the question of why it ICEs on x86-64 but not on x86.
And also of the info page 7.3 regarding garbage collection in the GNU (not
NeXT) runtime.

IIRC -fobjc-gc is only useful for the NeXT runtime.
