I guess this is > somewhat related to the Jiri's Fedora build fix. Building, linking of perf did not work (I think it was on a Fedora 27) resulting in an error message like: /usr/bin/ld: perf-in.o: `__printf_chk@@GLIBC_2.4' non-PLT reloc for symbol defined in shared library and accessed from executable (rebuild file with -fPIC ?) /usr/bin/ld: final link failed: Bad value On s390, objects must be compiled with -fPIC when used for shared object or position-indendepent executables (PIE). In doubt, it is better to build with -fPIC (there are no performance degration).
