improve Address Sanitizer (ASAN) support and chk_tree

Browse Source 
Updated BUGS about MSYS2 on Windows compiling of calc.

    Added more git related checks and sanity checks to chk_tree.

    Added ${FSANITIZE} make variable to Makefile.config to hold
    common Address Sanitizer (ASAN) optins to modern Linux and macOS.
    The Address Sanitizer is NOT enabled not compiled in by default.
    Improved comments in Makefile.local for RHEL9.2 (Linux) and for
    macOS 14.0 that, when uncommented and calc is recompiled (i.e.,
    make clobber all) will enable the Address Sanitizer (ASAN) for calc.
