Re: [PATCH 1/8] Use gcc attribute ifunc in libc_ifunc macro instead of inline assembly due to false debuginfo.

Okay. Then I can add an extra configure check to test the gcc attribute
ifunc support. If there is no support, a fallback ifunc-macro which uses
the old behaviour could be used. Then it won't break the build but the
debuginfo is not correct, too. Perhaps this fallback can be removed in
future. Do you know if gcc in Ubuntu 16.04 has ifunc support for ppc64le?
I would prefer if we could bump the minimum GCC and binutils version instead.
(I assume IFUNC support is not an optional feature in either tool which can be disabled at build time.) 

Thanks,
