riscv target spec for newlib and rtems

[Matt Wette]

The v5 source-builder does not work on python3 machines and current 
RTEMS release is 5.2 (or 5.1 if you go to www.rtems.org.   I did find 
v6.1-rc1  by guessing the path based on the 5.1 release path. I decided 
to take a shot at building on my own.   I've done this sort of thing 
before (e.g., building gcc 1.43 for VxWorks on 68k machines back in the 
'90s, before the days of autotools).   And, I wanted to see if I could 
get a guix build going.

I'll try the 6.1-rc1 also.

Thanks for the info

Matt
