While I have no particular interest in AIX or xlc specifically, I do
worry about us becoming a builds-on-gcc-or-workalikes-only project.
I suppose MSVC provides a little bit of a cross-check, but I don't
really like giving up on other compilers.  Discounting gcc+clang+MSVC
leaves just a few buildfarm animals, and the xlc ones are a significant
part of that population.  (In fact, unless somebody renews fossa/husky's
icc license, the three xlc animals will be an outright majority of
them, because wrasse and anole are the only other active animals with
non-mainstream compilers.)

Having said that, I don't plan to be the one trying to get meson
to add xlc support ...
