kbuild: simplify modname calculation
modname can be calculated much more simply. If modname-multi is empty, it is a single-used object. So, modname = $(basetarget). Otherwise, modname = $(modname-multi). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Cao jin <caoj.fnst@cn.fujitsu.com>
