Since 1.6.2, picolibc has had two releases - 1.7 and 1.7.1. Here are
the release notes from those versions.
1. Add __cxa_atexit implementation to 'picoexit' path as required by
C++
2. Fix lack of 'hh' support in integer-only tinystdio printf path.
3. Fix tinystdio __file flag initialization for C++ apps
1. Merge libc and libm into a single library. Having them split
doesn't offer any advantages while requiring that applications add
'-lm' to link successfully. Having them merged allows use of libm
calls from libc code.
2. Add hex float format to *printf, *scanf and strto{d,f,ld}. This is
required for C99 support.
3. Unify strto{d,f,ld} and *scanf floating point parsing code. This
ensures that the library is consistent in how floats are parsed.
4. Make strto{d,f,ld} set errno to ERANGE on overflow/underflow,
including when the result is a subnormal number.

Issue #1535
GCC 10 changed the default to -fno-common, which leads to a linking error in GLibc older than 2.30.
This change adds -fcommon cflag for the target GLibc versions <=2.29 and GCC >=10.
This change also adds additional cflags for the target GLibc to disable
new GCC11 checks that lead to compilation errors.

Add a single job to download (most of) the tarballs required. This
should allow the CI job to fail early when various sources are off-line
and prevent us from unintentionally DDoSing sites that we rely on.

Explicitly passing --disable-tm-clone-registry causes gcc to create a
crtbegin.o with a zero-sized .init_array/.fini_array. This in turn
causes ld to complain.
Make CC_GCC_TM_CLONE_REGISTRY a tristate so if it's not explicitly
enabled we can let ./configure decide.

Some of the installed libstdc++ header files use '#include_next' to
work around toolchain oddities that might cause loops in the
compiler. However, these also cause mistakes in locating header files
when there are multiple C libraries installed as '#include_next' often
ends up finding default C library header files.
It doesn't seem like this patch could be accepted upstream; there's a
long discussion about the use of include_next in these headers which I
cannot fully understand.

Prior to commit 30bffa96 SRC_CUSTOM was inside the choice with
SRC_RELEASE and SRC_DEVEL making the 3 options mutually exclusive.
Restore this behaviour keeping the "fix" to keep kconfig happy.

This commit adds a new gcc config `CT_CC_GCC_TM_CLONE_REGISTRY` that
enables the GCC transactional memory clone registry feature for libgcc.
Note that the gcc option to control this feature is only available in
gcc 10 and above.

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.

This commit adds two additional arguments (`cxxflags_for_target` and
`extra_cxxflags_for_target`) for the gcc backend build function that
can be used to specify custom target CXXFLAGS.
By default, the target CXXFLAGS is set to the target CFLAGS. When
`cxxflags_for_target` is specified however, it overrides that behaviour
and allows setting different target CXXFLAGS from the target CFLAGS.
The `extra_cxxflags_for_target` argument can be used to specify the
extra target CXXFLAGS to be appended to the target CXXFLAGS. This is
useful when it is necessary to append CXX-specific flags to the
existing CFLAGS to be used as the target CXXFLAGS.
A useful application of this is building full and nano versions of
libstdc++ with different target CXXFLAGS as necessitated by
`nano.specs`.

The gcc target libraries (e.g. libstdc++) are currently built without
any optimisation flag when `CT_CC_GCC_ENABLE_TARGET_OPTSPACE` is not
enabled and default to `-O0` unless user explicitly specifies an
optimisation flag.
This commit updates the gcc build script to assume `-O2` for building
target libraries unless user provides a different optimisation flag.
Note also that this is the default behaviour for gcc when
C[XX]FLAGS_FOR_TARGET is not overridden.
