Ping.  These patches

<https://sourceware.org/ml/libc-alpha/2018-05/msg00501.html>
<https://sourceware.org/ml/libc-alpha/2018-05/msg00541.html>

allow building libm.so.6 without GLIBC_PRIVATE references on aarch64, 
and on x86-64 if --disable-multi-arch is also specified (I have a patch 
to add multi-arch support for the latter, but I need to come up with 
something that reduces the maintenance burden).

Thanks,
Florian
