This uses the gcc support for building libstdc++ using alternate lib
header files.

This adds another mode to do_gcc_core_backend that builds libstdc++

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.

Currently the help for LOCAL_PATCH_DIR did not specify the tree layout
of custom patches directory. This commit adds such explanation.
For example, the bundled patches for GCC are placed under
packages/gcc/<gcc-version>, thus custom (local) GCC patches should be
placed under $LOCAL_PATCH_DIR/gcc/<gcc-version>.

When building powerpc64+glibc-2.32 we see the following error:

This seems to only trigger for powerpc64. Other architectures build
cleanly. For now avoid specifying -Werror for powerpc64+glibc-2.32.

Per the release notes for the GNU C library 2.28[1] make 4.0 or newer is

- Force building make as a companion tool if host make is older than
4.0 (CentOS 7 currently has 3.82)
- Disable 2.29 as a choice if host python is older than 3.4
(CentOS 7 has 2.6 unless python from EPEL is installed)
- Python2 emits its version information to STDERR. Ugh.
While there, also use the detected host Python for GDB configuration.
