NEWLIB_GLOBAL_ATEXIT needs to be set to y for modern newlib versions.
Commit 227d99d7 ("newlib: add 4.3.0.20230120") ensured this was done.
But xtensa-fsf-elf uses a newlib version from before this so it needs to
explicitly opt out.

*-moxie*: DTC_VERBOSE is a wobbler, it depends on whether dtc is enabled
on the host machine (if dtc is installed, DTC defaults to 'n' and hence
prevents DTC_VERBOSE from appearing at all). Remove the option from
config file so that its value reverts to the default.
xtensa-fsf-elf: mark configuration obsolete so that it can use GDB 8.1
(it uses custom sources and needs to select the version therein)
