Change libbpf.pc to list /usr/lib* instead of /usr/local/lib* in the linker flags (-L).
There is nothing installed in /usr/local by this package, and more importantly it breaks CMake builds of reverse dependencies as it gets added to the RPATH and it confuses SUSE's version of CMake:

[ 20s] file RPATH_CHANGE could not write new RPATH:
[ 20s]

[ 20s]
[ 20s] to the file:

[ 20s] /home/abuild/rpmbuild/BUILDROOT/dwarves-1.21+git175.1ef87b2-21.1.x86_64/usr/bin/codiff
[ 20s]
[ 20s] The current RUNPATH is:

[ 20s] /home/abuild/rpmbuild/BUILD/dwarves-1.21+git175.1ef87b2/build:

[ 20s] which does not contain:

[ 20s] /usr/local/lib64:/home/abuild/rpmbuild/BUILD/dwarves-1.21+git175.1ef87b2/build:

[ 20s] as was expected.
