From: Uwe Kleine-König Date: Tue, 22 Nov 2016 08:30:26 +0000 (+0100) Subject: make use of make variable CURDIR instead of calling pwd X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e19b7cee020441dd690613d223aed7abb0bcda81;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git make use of make variable CURDIR instead of calling pwd make already provides the current working directory in a variable, so make use of it instead of forking a shell. Also replace usage of PWD by CURDIR. PWD is provided by most shells, but not all, so this makes the build system more robust.
