With two adjustments from my previous message I can build with
GCC 8.0.0 20171004 (experimental) for armv7.  The issue is if we try
to do something as x86_64 does:

__hidden_ver1 (__new_memcpy, __GI_memcpy, __redirect_memcpy)
  __attribute__ ((visibility ("hidden")));

This indeed dump incompatible types with mainline GCC.
