commit 8038e2f7548792a090bdd255ec6bfbf4128fead7
Author: Antonio Borneo <bor...@gm...>
Date:   Sun Nov 17 22:46:15 2024 +0100

    configure: allow --enable-malloc-logging only with glibc
    
    The feature for 'malloc-logging' uses functionalities that are
    available only in GNU libc.
    
    Detect in 'configure' if OpenOCD is being compiled with glibc.
    Set the macro '_DEBUG_FREE_SPACE_' only in case of glibc.
