kbuild: revert $(realpath ...) to $(shell cd ... && /bin/pwd)
I thought commit 8e9b46679923 ("kbuild: use $(abspath ...) instead of
$(shell cd ... && /bin/pwd)") was a safe conversion, but it changed
the behavior.
$(abspath ...) / $(realpath ...) does not expand shell special
characters, such as '~'.
Here is a simple Makefile example:
---------------->8----------------
$(info /bin/pwd: $(shell cd ~/; /bin/pwd))
$(info abspath: $(abspath ~/))
$(info realpath: $(realpath ~/))
all:
@:
---------------->8----------------
$ make
/bin/pwd: /home/masahiro
abspath: /home/masahiro/workspace/~
realpath:
This can be a real problem if 'make O=~/foo' is invoked from another
Makefile or primitive shell like dash.
This commit partially reverts 8e9b46679923.
Fixes: 8e9b46679923 ("kbuild: use $(abspath ...) instead of $(shell cd ... && /bin/pwd)")
