Rather than dropping bdftruncate entirely, perhaps simply put it in its
own subpackage? You wouldn't need it to Require anything (the perl deps
will be autogenerated), nor would xorg-x11-font-utils need to Require
the bdftruncate subpackage, effectively solving the problem without
dropping (semi) useful code.

%package -n bdftruncate
Summary: Generate truncated BDF font from ISO 10646-1 encoded BDF font
Group:	 Applications/System

%description -n bdftruncate
bdftruncate allows one to generate from an ISO10646-1 encoded BDF font
other ISO10646-1 BDF fonts in which all characters above a threshold
code value are stored unencoded. This is often desirable because the
Xlib API and X11 protocol data structures used for representing font
metric information are extremely inefficient when handling sparsely
populated fonts.

...

%files -n bdftruncate
%defattr(-,root,root,-)
%{_bindir}/bdftruncate
%{_mandir}/bdftruncate.*
