Hi Guys,

  I am applying the attached patch to sync the top level configure.ac,
  Makefile.def and Makefile.tpl files with the versions on the gcc
  mainline development branch.

  This update brings in the following commits:

    Pass GUILE down to subdirectories
    
    When I enable cgen rebuilding in the binutils-gdb tree, the default is
    to run cgen using 'guile'.  However, on my host, guile is guile 2.2,
    which doesn't work for me -- I have to use guile3.0.
    
    This patch arranges to pass "GUILE" down to subdirectories, so I can
    use 'make GUILE=guile3.0'.

    build: Add libgrust as compilation modules
    
    Define the libgrust directory as a host compilation module as well as
    for targets. Disable target libgrust if we're not building target
    libstdc++.

    Makefile.tpl: Avoid race condition in generating site.exp from the top level
    
    A command like "make -j 2 check-gcc-c check-gcc-c++" run in the top level of
    a fresh build directory does not work reliably. That will spawn two
    independent make processes inside the "gcc" directory, and each of those
    will attempt to create site.exp if it doesn't exist and will interfere with
    each other, producing often a corrupted or empty site.exp. Resolve that by
    making these targets depend on a new phony target which makes sure site.exp
    is created first before starting the recursive makes.

    Config,Darwin: Allow for configuring Darwin to use embedded runpath.
    
    Recent Darwin versions place contraints on the use of run paths
    specified in environment variables.  This breaks some assumptions
    in the GCC build.
    
    This change allows the user to configure a Darwin build to use
    '@rpath/libraryname.dylib' in library names and then to add an
    embedded runpath to executables (and libraries with dependents).
    
    The embedded runpath is added by default unless the user adds
    '-nodefaultrpaths' to the link line.
    
    For an installed compiler, it means that any executable built with
    that compiler will reference the runtimes installed with the
    compiler (equivalent to hard-coding the library path into the name
    of the library).
    
    During build-time configurations  any "-B" entries will be added to
    the runpath thus the newly-built libraries will be found by exes.
    
    Since the install name is set in libtool, that decision needs to be
    available here (but might also cause dependent ones in Makefiles,
    so we need to export a conditional).
    
    This facility is not available for Darwin 8 or earlier, however the
    existing environment variable runpath does work there.
    
    We default this on for systems where the external DYLD_LIBRARY_PATH
    does not work and off for Darwin 8 or earlier.  For systems that can
    use either method, if the value is unset, we use the default (which
    is currently DYLD_LIBRARY_PATH).

    Makefile.tpl: disable -Werror for feedback stage [PR111663]
    
    Without the change profiled bootstrap fails for various warnings on
    master branch as:
    
        $ ../gcc/configure
        $ make profiledbootstrap
        ...
        gcc/genmodes.cc: In function ‘int main(int, char**)’:
        gcc/genmodes.cc:2152:1: error: ‘gcc/build/genmodes.gcda’ profile count data file not found [-Werror=missing-profile]
        ...
        gcc/gengtype-parse.cc: In function ‘void parse_error(const char*, ...)’:
        gcc/gengtype-parse.cc:142:21: error: ‘%s’ directive argument is null [-Werror=format-overflow=]
    
    The change removes -Werror just like autofeedback does today.

    Pass 'SYSROOT_CFLAGS_FOR_TARGET' down to target libraries [PR109951]
    
    ..., where we need to use it (separate commits) for build-tree testing, similar
    to 'gcc/Makefile.in:site.exp':
    
        # TEST_ALWAYS_FLAGS are flags that should be passed to every compilation.
        # They are passed first to allow individual tests to override them.
            @echo "set TEST_ALWAYS_FLAGS \"$(SYSROOT_CFLAGS_FOR_TARGET)\"" >> ./site.tmp
    
            PR testsuite/109951
            * Makefile.tpl (BASE_TARGET_EXPORTS): Add
            'SYSROOT_CFLAGS_FOR_TARGET'.
            * Makefile.in: Regenerate.
