From e19b7cee020441dd690613d223aed7abb0bcda81 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Tue, 22 Nov 2016 09:30:26 +0100 Subject: make use of make variable CURDIR instead of calling pwd MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
