These days old v5 ABI is not that relevant as it used to be back in
2015 when ncurses 6.x was added to CT-NG.
And now we see say target "gdb" relying on "libncurses.so.5",
while up-to-date Buildroot provides "libncurses.so" & "libncurses.so.6":
--------------------------->8-------------------------
$ ldd /bin/gdb
libncurses.so.5 => not found
libstdc++.so.6 => /lib/libstdc++.so.6 (0x20022000)
libm.so.6 => /lib/libm.so.6 (0x2017c000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x201ba000)
libc.so.6 => /lib/libc.so.6 (0x201c8000)
/lib/ld-linux-arc.so.2 (0x20000000)
--------------------------->8-------------------------
Switching to a default (v6 ABI) by default. And...
--------------------------->8-------------------------
$ ldd /bin/gdb
libncurses.so.6 => /usr/lib/libncurses.so.6 (0x20022000)
libstdc++.so.6 => /lib/libstdc++.so.6 (0x20054000)
libm.so.6 => /lib/libm.so.6 (0x201ae000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x201ec000)
libc.so.6 => /lib/libc.so.6 (0x201fa000)
/lib/ld-linux-arc.so.2 (0x20000000)

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.

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.

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

This allows building newlib-nano in addition to newlib and picolibc,
allowing users to select between C libraries within the same toolchain.

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.

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.

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.
Signed-off-by: Alexey Neyman <stilor@att.net>
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).
