--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
lto-wrapper.cc use MAKE env if it exists:
          char **make_argv = buildargv (getenv ("MAKE"));
          if (make_argv)
            {
              for (unsigned argc = 0; make_argv[argc]; argc++)
                obstack_ptr_grow (&argv_obstack, make_argv[argc]);
            }
          else
            obstack_ptr_grow (&argv_obstack, "make");

          obstack_ptr_grow (&argv_obstack, "-f");
          obstack_ptr_grow (&argv_obstack, makefile);
          if (!jobserver)
            {
              snprintf (jobs, 31, "-j%ld",
                        auto_parallel ? nthreads_var : parallel);
              obstack_ptr_grow (&argv_obstack, jobs);
            }

But I don't see why gmake is failing to set MAKE env correctly here ...
