Hi Oliver,

The reproducer script doesn't manage to build (I'm using Fedora 39):

+ /usr/lib/rpm/check-rpaths
*******************************************************************************
*
* WARNING: 'check-rpaths' detected a broken RPATH OR RUNPATH and will cause
*          'rpmbuild' to fail. To ignore these errors, you can set the
*          '$QA_RPATHS' environment variable which is a bitmask allowing the
*          values below. The current value of QA_RPATHS is 0x0000.
*
*    0x0001 ... standard RPATHs (e.g. /usr/lib); such RPATHs are a minor
*               issue but are introducing redundant searchpaths without
*               providing a benefit. They can also cause errors in multilib
*               environments.
*    0x0002 ... invalid RPATHs; these are RPATHs which are neither absolute
*               nor relative filenames and can therefore be a SECURITY risk
*    0x0004 ... insecure RPATHs; these are relative RPATHs which are a
*               SECURITY risk
*    0x0008 ... the special '$ORIGIN' RPATHs are appearing after other
*               RPATHs; this is just a minor issue but usually unwanted
*    0x0010 ... the RPATH is empty; there is no reason for such RPATHs
*               and they cause unneeded work while loading libraries
*    0x0020 ... an RPATH references '..' of an absolute path; this will break
*               the functionality when the path before '..' is a symlink
*          
*
* Examples:
* - to ignore standard and empty RPATHs, execute 'rpmbuild' like
*   $ QA_RPATHS=$(( 0x0001|0x0010 )) rpmbuild my-package.src.rpm
* - to check existing files, set $RPM_BUILD_ROOT and execute check-rpaths like
*   $ RPM_BUILD_ROOT=<top-dir> /usr/lib/rpm/check-rpaths
*
