[PATCH 6/6] kbuild: check clean srctree even earlier

From: Masahiro Yamada
Date: Thu Aug 22 2019 - 09:43:56 EST


Move the outputmakefile target to the leftmost in the prerequisite list
so that this is checked first. There is no guarantee that Make runs the
prerequisites from left to right, but at least the released versions of
GNU Make work like that when the parallel build option is not given.

Of course, when the parallel option -j given, other targets will be run
simultaneously but it is nice to show the error as early as possible.
