As phrased, this seems to be saying that we can do both
endiannesses on any of the supported arches, which is a little
weird considering that most of them are single-endianness. It's
not a big deal, but maybe a tad more word-smithing there would
help?

Agreed. In principle I'd wish that we were not tied to one
floating-point format, but the benefits of Ryu are too hard to
pass up; and reality on the ground is that IEEE 754 achieved
total victory a couple decades ago. We should stop claiming
that VAX is a realistic target platform.

WFM. Also, that crypt-blowfish.c hunk offers an answer to
your question about whether to worry about "__hppa".
