* arm/configure.in: Check the value of newlib-may-supply-syscalls
        enablement variable to determine if crt0 should or should not be
        built.
        * arm/configure: Regenerated.
        * arm/Makefile.in: Changed to look at @BUILD_CRT0_TRUE@ and
        @BUILD_CRT0_FALSE@ variables set in configure to determine
        if crt0.o should be built and installed.
