Detect support for nextafterf in RKTest
As described in the nextafterf(3) man page for glibc, we check for the POSIX version and then provide our own definition of nextafterf if glibc does not.
Is this something you would be interested in adding? There are some platforms which don't provide this function and it appears that checking for this POSIX version detects support correctly on Ubuntu 20.04 and in my particular use case. The nextafterf definition was pulled from musl-libc and it appears the project is MIT licensed.
I guess this would be a good addition, my only thought is how to best integrate this while keeping rktest.h a single-header library
Also, isn't nextafterf guaranteed to exist for C99? This is meant to be a C99 library. Maybe I'm misreading the manpage https://linux.die.net/man/3/nextafterf
Can you merge main into this branch? I think external pull requests should be able to run the tests now

No, you're right. This change doesn't really align with RKTest's goals. I did this a while ago and now I can't remember why the library I'm using doesn't provide nextafterf. I'll close this for now.
