    Fixed table with list of supported builds

    The mingw builds were still reported in the table of supported
    toolchains as not supported.
    Removed the extra column as all the listed toolchains are now supported
    for building.

commit d9053860
Author: Alex Coplan <alex.coplan@arm.com>
Date:   Fri Apr 26 12:57:40 2024 +0100

    Fix aarch64-none-linux-gnu build for morello

    This fixes an issue in build-cross-linux-toolchain.sh which was causing the
    build to fail when attempting to build a Morello Linux toolchain as follows:

    ./build-gnu-toolchain.sh --target=aarch64-none-linux-gnu --morello

    The problem was that in the libc{,-headers} stages, the variable
    libc[_headers]_extra_config_envflags lost some quotes around the operands to the
    ternary invocation inside the CC=, CXX= lines.  In particular, this meant that
    instead of setting:

    CC=aarch64-none-linux-gnu-gcc -mabi=purecap -march=morello+c64

    it would just set:

    CC=aarch64-none-linux-gnu-gcc

    and this eventually caused the gcc2 build to attempt to link vanilla A64
    objects (libc crt files) into a purecap libgcc.

    This patch fixes the issue by using heredocs around the definitions of
    the appropriate extra_config_envflags variables and inserting double
    quotes around the operands to the ternary invocations.

    Tested by building a Morello toolchain as described above.

    GNUTOOLS-14765 Clean command errors

    The "clean" stage removes all directories and run the "start" stage, at
    which point the installdir is lost and the error rises:
    this was introduced by refactoring here:
    https://eu-gerrit-1.euhpc.arm.com/c/dsg-gnu/Internal/oban-scripts/+/566141/3/build-elf.sh#682

    Implemented a generic mk_bin_dirs in utilities
    Invoking the function in start stage so that in case of cleanup and
    start, the directories are created.

    Also fixed build-cross script which has a similar defect
