master a79c578 5/5: Port test module to glibc 2.33

[Paul Eggert]

branch: master
commit a79c578f3d77101964b837e8fa8b8109f21c7a88
Author: Paul Eggert <eggert@cs.ucla.edu>
Commit: Paul Eggert <eggert@cs.ucla.edu>

    Port test module to glibc 2.33
    
    * test/Makefile.in (REPLACE_FREE, FREE_SOURCE_0, FREE_SOURCE_1):
    New macros.
    ($(test_module)): Improve accuracy of test as to whether free.c
    should be compiled; glibc 2.33 does not need it compiled and the
    compilation breaks if you try, if you build with
    --enable-gcc-warnings.
