[PATCH 4/8] kbuild: turn '/' into an alias of './'

From: Masahiro Yamada
Date: Wed Feb 13 2019 - 22:06:32 EST


Commit 06300b21f4c7 ("kbuild: support building individual files for
external modules") introduced the '/' target. It works only for
external modules to build all .o files, but skip the modpost stage.

However, 'make /' looks a bit weird to me. 'make ./' is more sensible
if you want to build all objects under the current directory, and it
works as expected.

Let's change '/' into a phony target that is an alias of './', but
I may feel like deprecating it in the future.
