GCC 9 on PowerPC is doing well. I was able to test on GCC110 and
GCC112 from the compile farm. I tested both a regular build (not much
more than -DNDEBUG -g2 -O3) and a UBsan build (-fsanitize=undefined).

One thing that was slightly unusual during the build with gcc-9 was
undefined references when using UBsan. I had to manually specify both
-lrt and -ldl:

    $ LDLIBS="-lrt -ldl" CXX=/home/mik/misc/gcc-9/bin/g++-9 make ubsan
    ...

It is unusual because I have never had to add libraries for GCC before.

I mention it in case it is something that the devs would like to address.
