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. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Michal Marek <mmarek@suse.com>
