STR-750: Obey the OpenSUSE package conventions (libexec)
SUSE doesn’t use libexec:
libexecdir in the RPM spec file is set to prefix/libSubmitted on 14 April 2008 at 00:11
We override that for now, due to problems with STR-749.
Need to revert the libexec hack in the spec file once STR-749 has been fixed.
