In that case the key question is whether consensus can be reached for 
requiring GCC 6.1 or later (supposing 6.1 has all the required support, 
both complex arithmetic and the handful of built-in functions for 
__float128 present on other architectures with __float128 support) to 
build glibc 2.25 for PPC64LE (without requiring it for other architectures 
including big-endian powerpc).  I don't know what the views of the PPC64LE 
glibc community on such a requirement might be.  (If you propose such a 
version requirement and no-one objects, then as architecture maintainer 
you can take that to be consensus.)
