A toolchain uclibc-ng-1.0.43, binutils-2.40 and gcc-13.2.0 hits the
following error when building:
ld.bfd: isl_test2.o: non-canonical reference to canonical protected function `__pthread_key_create' in x86_64-multilib-linux-uclibc/sysroot/lib64/libc.so.1
ld.bfd: failed to set dynamic section sizes: bad value
The reference comes from libgcc where it is using the
__pthread_key_create() symbol to detect the use of pthreads with GNU
libc. Prevent this on uclibc-ng with an explicit condition.

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.

glibc-2.28 complains:
configure: error: use a compatible toolchain or configure with --disable-mathvec (this results in incomplete ABI).
Apparently this is a problem in the way GCC passes the -mcpu and -march
values to the assembler. As a workaround have the configure check pass
-mcpu as well to override anything we're passing in the environment.
Patch and explanation taken from the Yocto project with thanks.

CC_CC_GCC_ENABLE_DEFAULT_PIE=n is invalid Kconfig syntax for an option
that was intentionally disabled the saved config would be
'# CC_CC_GCC_ENABLE_DEFAULT_PIE is not set'
but the DEFAULT_PIE option isn't selectable for RISCV && BARE_METAL so
the correct thing to do is just remove the config.
This also picks up a change regenerating the saved sample due to changes
in the Kconfig ordering.

Due to the small flash space on AVR devices the library containing the
standard types in C++ (ˋlibstdc++ˋ) does not get built normally when
enabling the C++ language support.
This option is an easy way to go back to the PC-way where ˋlibstdc++ˋ is
built.

The missing quotes affect bootstrap routine:

Versions of GNU make newer than 4.4 trigger a hang in versions of glibc
older than 2.31. As distros update to the newer GNU make version we'll
start seeing more and more reports of this hang. Fortunately we already
carry GNU make as a comp tool so all we need to do is select the right
version when needed.

This reverts commit 658f5e574f, which
was made without any justification, and prevents using crosstool-ng
even in decently recent distributions like Ubuntu 20.04 (which has
autoconf 2.69).
We have tested that ./bootstrap && ./configure --enable-local works
fine on Ubuntu 18.04, which uses autoconf 2.69 and automake 1.15, so
the existing requirements were enough.

Use a relative path for include directory if gdb or gdbserver
is being built and installed for a target. Otherwise headers
are installed in ${destdir}${CT_HEADERS_DIR} - a concatenation
of ${destdir} and an absolute path to sysroot's include directory.
As a result debug-root may contain wrong paths for includes.
