kbuild: clean up scripts/gcc-version.sh
Now that the Kconfig is the only user of this script, we can drop unneeded code. Remove the -p option, and stop prepending the output with zero, so that Kconfig can directly use the output from this script. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
