commit db27f1251b008280a29d540b4f8ab2a38a0d80af
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date:   Wed Jan 12 23:34:23 2022 +0530

    debug: Autogenerate _FORTIFY_SOURCE tests
    
    Rename debug/tst-chk1.c to debug/tst-fortify.c and add make hackery to
    autogenerate tests with different macros enabled to build and run the
    same test with different configurations as well as different
    fortification levels.
    
    The change also ends up expanding the -lfs tests to include
    _FORTIFY_SOURCE=3.
