  It requires less boilerplate code for newer ports.  The _Static_assert
checks from internal setjmp are moved to its own implementation since
setjmp.h is included early by multiple headers (to generate
rtld-sizes.sym).

The riscv jmp_buf-macros.h check is also redundant, it is already
done by riscv configure.ac.

Checked with a build for the affected architectures.

Shouldn't this be an internal test?

I checked the generated constants against the removed files, and found
no discrepancies, so I think this can go in.

Thanks,
Florian

My understanding is the _Static_assert would be more useful at build time,
specially for cross-compilation.

An internal will still have the same effect when cross-compiled.

I don't have a strong preference in fact, I think an object consumes slight
less resources through (cpu time to build, disk size).

It consumes space in the installed artifacts, though.

Hum I forgot to verify this, I will change to an internal test.
