Hi Jeff,
I believe the patch is correct. Not all glibcs support IFUNC. It doesn't mean
we should disable IFUNC for all glibcs. By default, we do a configure time
check for IFUNC. We DO want to use configure time check for IFUNC for
Android NDK.

I'm sorry, I'm objecting to this patch. It is wrong for GCC to produce
code that is incorrect solely for the benefit of optimizing for a new
release of a library.
The right way is to trigger the new code on some configure time option
or a new configuration itself.
Whether or not GCC is doing this right for glibc is irrelevant, the
patch is _wrong_.
