7144b5f275 newlib: Add libstdc++ nano-specific CXXFLAGS
This commit adds a new config that can be used to specify the target
CXXFLAGS specific to the libstdc++ newlib-nano variant.

By default, this config is set to specify the `-fno-exceptions` option,
which disables C++ exception handling support and greatly reduces the
compiled binary size.

8e99639419 newlib-nano: Add option to copy libs into target
Add an option that will install a copy of newlib-nano lib*.a file in
the target dir but renamed with a nano.a suffix (eg: libc_nano.a) as
some default nano.spec files from newlib expect this setup.

Additionally the newlib-nano version of newlib.h will get copied to
include/newlib-nano/newlib.h.

e7d0485ca2 Add package with PRU linker scripts and headers
Include the gnuprumcu package in PRU cross toolchain.
Toolchain is somewhat useless without device specs and
linker scripts for the various SoCs.

945b4c6436 Add newlib-nano as companion lib
This allows building newlib-nano in addition to newlib and picolibc,
allowing users to select between C libraries within the same toolchain.

74949b1d35 picolibc: Clean up configuration a bit
Use LIBC_PICOLIBC_CXA_ATEXIT to keep this name in the same 'namespace'
as the other picolibc config names.

Enable retargetable locking by default. This allows the few locks in
picolibc to be implemented by the execution environment, rather than
disabling the locking code.

Also, remove a couple of config options that dealt with package versions
that have been since retired.

66ad1ff514 Upgrade to new releases
android-ndk, binutils, gcc, linux, mpfr, ncurses, newlib, uclibc-ng

MPC vs MPFR dependencies required modifications in auto-generated templates
to also provide non-inclusive older-than/newer-than specifications.

Also correct MPC URLs, the website seems to have adjusted its directory
layout.

Currently, newlib 3.0.0 doesn't build for arm-nano-eabi.

9fdb93cce0 Make comp.libs use generated templates, too
This allows us to include the component-to-package relation in the
generated kconfig files and make use of that information in the
show-config.sh script.

ff0a1a3da6 Switch gen-kconfig to new framework
Also:
- Move companion_* to comp_* to match the kconfig symbols
- Replace bootstrap with former gen-versions.sh
- Fold *.in.2 into their respective first parts; this moves common
  options to the end - if it is undesirable, inclusion of *.in
  can be moved where *.in.2 used to be (but that will also move
  version selection after common options).
- Retire addToolVersion.sh (may later replace with a more
  comprehensive script that tries to download the added tarballs,
  copy the patches and try to apply them, and create a version.desc).
