Dear Newlib Maintainers,

I have updated the following on my initial patch:

1) Added Makefile entries to build new file
2) Edited definition of SIG2STR_MAX as discussed
3) Added code for "RTMAX-m" in sig2str
4) Added check for whether RTMIN==RTMAX
5) Removed <signum> from "Unknown signal" error message. I reasoned
that this would be ok because the standard does not mention any
error message anyway and it could potentially avoid problems with
the length of the string representation of the invalid signum
exceeding the length of the SIG2STR_MAX sized buffer.

Standing by for any further feedback. Thank you very much for your
