fltk rebuild issue: uname -i "unknown"?

I haven't paid much attention to the fltk package since Rex is the primary maintainer but I just attempted to build fldigi and ran into the following issue: checking for fltk-config... /usr/bin/fltk-config /usr/bin/fltk-config: line 3: exec: fltk-config-unknown: not found configure: error: /usr/bin/fltk-config failed From a local rebuild attempt of fltk I see: + mv /builddir/build/BUILDROOT/fltk-1.3.8-3.fc38.x86_64/usr/bin/fltk-config /builddir/build/BUILDROOT/fltk-1.3.8-3.fc38.x86_64/usr/bin/fltk-config-unknown + install -p -m755 -D /builddir/build/SOURCES/fltk-config.sh /builddir/build/BUILDROOT/fltk-1.3.8-3.fc38.x86_64/usr/bin/fltk-config Which seems strange until I took a loot at the FLTK specfile: # we only apply this hack to multilib arch's %ifarch x86_64 %{ix86} ppc64 ppc s390x s390 sparc64 sparc %global arch %(uname -i 2>/dev/null || echo undefined) mv $RPM_BUILD_ROOT%{_bindir}/fltk-config \ $RPM_BUILD_ROOT%{_bindir}/fltk-config-%{arch} install -p -m755 -D %{SOURCE1} $RPM_BUILD_ROOT%{_bindir}/fltk-config %endif Obviously this has been in place for a VERY long time but the only use case I can think of is to have fltk-devel installed from two different arches, i686 and x86_64 for instance. Could this have anything to do with the systemd-nspawn change? Could it have caused `uname -i` to no longer resolve correctly? Does this really need to be supported at this point? Thanks, Richard
