Subject: [PATCH 4.14 001/140] kbuild: move "_all" target out of $(KBUILD_SRC) conditional

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Masahiro Yamada <yamada.masahiro@...ionext.com>

commit ba634eceb535d95e87ef09caae7814b3687c6036 upstream.

The first "_all" occurrence around line 120 is only visible when
KBUILD_SRC is unset.

If O=... is specified, the working directory is relocated, then the
only second occurrence around line 193 is visible, that is not set
to PHONY.

Move the first one to an always visible place.  This clarifies "_all"
is our default target and it is always set to PHONY.
