kbuild: sort hostprogs before passing it to ifneq
The conditional: ifneq ($(hostprogs),) ... is evaluated to true if $(hostprogs) does not contain any word but whitespace characters. ifneq ($(strip $(hostprogs)),) ... is a safe way to avoid interpreting whitespace as a non-empty value, but I'd rather want to use the side-effect of $(sort ...) to do the equivalent. $(sort ...) is used in scripts/Makefile.host in order to drop duplication in $(hostprogs). It is also useful to strip excessive spaces. Move $(sort ...) before evaluating the ifneq. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
