Subject: build-sys: be more tolerant if dbus directories do not exist
X-Git-Tag: v198~96
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=03c149144d374cffd40a17ffb067837e3e220933

build-sys: be more tolerant if dbus directories do not exist

use readlink -m instead of -f since we might be building in a minimal
chroot where those directories do not actually exist and readlink -f
would return an empty string.
