        * configure.ac (gcc_version): Set near the beginning.
        (as, ld, nm): Do not link in-tree tools.  Set gcc_cv_* if tools are
        found in the tree.  Use gcc_AC_PROG to find the tools in the system.
        (objdump): Do not look for it.
        * Makefile.in (NM_FOR_TARGET): Point to ./nm.
        (ORIGINAL_AS_FOR_TARGET, ORIGINAL_LD_FOR_TARGET,
        ORIGINAL_NM_FOR_TARGET): Substitute from autoconf.
        (as, ld, nm): New rules.
        (libgcc.mk): Depend on them.
        * aclocal.m4 (gcc_AC_TOOL_DIRS, gcc_AC_CHECK_TOOL,
        gcc_AC_BUILD_EXEEXT): New.
        (gcc_AC_CHECK_PROG_VER): Use gcc_AC_BUILD_EXEEXT.
        * configure: Regenerate.
