when build on openSUSE Build Serice,
SUSE_DETECTED will be "FALSE", because the file /etc/SuSE-release in not exist.
In OBS, the package " openSUSE-release" which contains the file /etc/SuSE-release
will not be installed by default.
I do it manually by passing the env var SUSE_DETECTED="TRUE" to make,
works fine too.
Thank you very much.
