    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.
