Masahiro Yamada 8e9b466799 kbuild: use $(abspath ...) instead of $(shell cd ... && /bin/pwd) ... Kbuild conventionally uses $(shell cd ... && /bin/pwd) idiom to get the absolute path of the directory because GNU Make 3.80, the minimal supported version at that time, did not support $(abspath ...) or $(realpath ...). Commit 37d69ee308 ("docs: bump minimal GNU Make version to 3.81") dropped the GNU Make 3.80 support, so we are now allowed to use those make-builtin helpers. This conversion will provide better portability without relying on the pwd command or its location /bin/pwd. I am intentionally using $(realpath ...) instead $(abspath ...) in some places. The difference between the two is $(realpath ...) returns an empty string if the given path does not exist. It is convenient in places where we need to error-out if the makefile fails to create an output directory.
