This is a merge commit bringing together multiple topics, so it's difficult to say which topic may have caused a regression. Perhaps try git-bisect to narrow the problem down to a single commit.

Your config.log shows that it is trying to test-compile this tiny program:

    /* confdefs.h */
    #define PACKAGE_NAME "git"
    #define PACKAGE_TARNAME "git"
    #define PACKAGE_VERSION "2.42.GIT"
    #define PACKAGE_STRING "git 2.42.GIT"
    #define PACKAGE_BUGREPORT "git@vger.kernel.org"
    #define PACKAGE_URL ""
    /* end confdefs.h.  */
    int
    main (void)
    {
      ;
      return 0;
    }

with the simplest command `gcc conftest.c`, but it's failing. Perhaps try compiling that program manually in your `/home/haomi/git' directory and see what the result is (also check $?).
