Not with GCCs built by myself (GCC 6.2 and 7.1 (release tags) and GCC 8
(248932)), which is what I used in the tests.  None of them produced a
libc.so that contained have_ieee_hw_p.

I'm still trying to understand what's the difference between my compilers
and those from build-many-glibcs.py, but one of our suspects is that the
assembler on my machine does not have support for POWER9.
