build-many-glibcs.py does not use any special configure options in GCC or
glibc to select a particular processor (which I think means a POWER8
default in GCC; I don't think powerpc glibc yet determines which sysdeps
directories to use based on compiler defaults, however, though we've
discussed that this approach, as used by the ARM port, is to be preferred
over --with-cpu).
