Lots of recent picolibc news:
* Oliver Stannard at ARM got testing running on the FVP emulator for more rigorous AARCH64 validation.
* Eduard Tanase fixed a bunch of documentation issues.
* Joel Holdsworth added OpenRisc support.
* Jiaxun Yang fixed my janky tools situation by creating picolibc-ci-tools which auto-builds all of the extra bits we need for CI. They also add LoongArch and LatticeMico32 support. The latter uncovered GCC bugs which I had fun fixing.
Thanks to all of you!
