Subject: [PATCH] Makefile: One last adjustment to relative paths

From: Boaz Harrosh <boaz@...xistor.com>

I have one last problem when compiling under an IDE. This
time it is when I compile linux under another Makefile
with the use of
	make -C linux

The make command is run from /home/boaz/dev/
What the IDE will see is:
make[1]: Entering directory `/home/boaz/dev/linux-open-osd'

	This one is from the external make dev/Makefile

make[1]: Entering directory `.build_um'

       ^ This one is emulated by Linux Makefile
       ...

make[1]: Entering directory `.build_um'

       ^ This one is emulated by Linux Makefile again
error: ../foo/baz.c:XXX
       ...

The IDE will look for ../foo/baz.c at
	/home/boaz/dev/.build_um/../foo/baz.c ==
	/home/boaz/dev/foo/baz.c

This is because make will always print its "Entering directory"
full path or relative to the original make command, this is
make -C rules.

the simple fix is to have "Entering directory" print full path.
