commit b54d9711f53daf5fd80d42ec9d2802dac0856c3e

    Configuration: checking if static libraries can be built
    
    Until this commit, Gnuastro didn't check if the static libraries could be
    built. However, it may happen that in some systems it is not possible and
    then a crash occurs. This is actually what happens in macOS.
    
    With this commit, this problem has been fixed by checking if the compiler
    is able to build the static libraries. Now it checks if static libraries
    can be built. If it is possible, then it will do it. If it is not possible,
    then no static libraries will be created and a warning is printed as an
    output.
    
    This fix has been done with the help of Mohammad Akhlaghi, and it fixes the
    bug #62590 (https://savannah.gnu.org/bugs/index.php?62590).
