[PATCH 3/4] kbuild: pkg: rename scripts/package/Makefile to scripts/Makefile.package

From: Masahiro Yamada
Date: Wed Aug 21 2019 - 03:04:31 EST


scripts/package/Makefile does not use $(obj) or $(src) at all.
It actually generates files and directories in the top of $(objtree).
I do not see much sense in descending into scripts/package/.
