H A DMakefilediff 16f8259c Sun Nov 05 02:44:16 MST 2017 Bjørn Forsman <bjorn.forsman@gmail.com> kbuild: /bin/pwd -> pwd

Most places use pwd and rely on $PATH lookup. Moving the remaining
absolute path /bin/pwd users over for consistency.

Also, a reason for doing /bin/pwd -> pwd instead of the other way around
is because I believe build systems should make little assumptions on
host filesystem layout. Case in point, we do this kind of patching
already in NixOS.

Ref. commit 028568d84da3cfca49f5f846eeeef01441d70451
("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.
