--- Comment #3 from Petr Pisar  ---
I read Module::Build::XSUtil, and it does not do anything special regarding the
order of object files and linker flags. Module::Build::XSUtil inherits from
Module::Build. I checked perl-RPM2 that also uses Module::Build, and the issue
manifests there either:

gcc -lpthread -shared -Wl,-z,relro -Wl,--as-needed -Wl,-z,now
-specs=/usr/lib/rpm/redhat/redhat-hardened-ld -L/usr/local/lib
-fstack-protector-strong -lperl -o blib/arch/auto/RPM2/RPM2.so lib/RPM2.o -lrpm
-lrpmio

I conclude this is a bug in perl-Module-Build.
