Yeah, looks like there are quite a few fixes in picolibc that I haven't
had time to send over to newlib.
I've also fixed a bunch of exception problems when compiling with clang,
which is happy to evaluate expressions known at compile time, even
though that doesn't generate exceptions at runtime. (things like 'return
one/zero;')
I've also generated tests for return values, exceptions and errnos for
the math functions to make sure they match the relevant specs and also
match glibc (mostly as a way to check the tests).
Anyone is welcome to pull those fixes out of picolibc and get them into
newlib; I probably won't have time for a while.
