That's for https://gcc.gnu.org/install/specific.html

[I did notice (just before submitting) that the bullet list
 was incomplete - hence, I added it. (Also one ref missed a '-x'.)
 However, main reason for this patch is for GCN:]

The listed LLVM version for GCN was outdated.

For newlib, I also decided to change from a date/hash-based
versioning to a release version - for both nvptx and gcn.

[There are some reasons to recommend 4.3.0 once released (or current git),
but those fixes are only very nice and not strictly required. (See below.)]

OK for mainline + GCC 12 backport?

* * *

Regarding newlib:

* Last release:
- 4.2.0 (Dec 2021, end of year snapshot, "newlib-snapshot-20211231" git tag)

* GCN
- The last bugfix was 2019-11-07, but that's also in 3.2.0
  but after the previously listed date
- Afterwards, there was only fix after the Makefile reorg (2022-03-21)
  but that's a post 4.2.0 change. For some reasons, reorg also exposed
  a preexisting issue ("I'm not sure how this ever worked?")

* nvptx: More recent nvptx changes:
- fix calloc for nvptx: "Fix Bug libc/28945" (Mar 22) - next annual snapshot
- "newlib: Only call _fputwc_r if ELIX_LEVEL >= 4" (Mar 22) - next annual snapshot
- "nvptx: Emulate clock and other machine stubs." (Aug 21) - in 4.2.0

Now committed as obvious (+ Andrew's LGTM on IRC) as https://gcc.gnu.org/r13-3056-ge886ebd17965d78f609b62479f4f48085108389c

Thanks,
