Odd debugedit message: -b arg has to be either the same length as -d arg, or more than 1 char longer

[David Howells]

I'm seeing this message:

extracting debug info from /home/dhowells/rpmbuild/BUILDROOT/cross-gcc-4.9.0-2.fc21.x86_64/usr/lib/gcc/hppa-linux-gnu/4.9.0/libcloog-isl.so.4
/usr/lib/rpm/debugedit: -b arg has to be either the same length as -d arg, or more than 1 char longer

but only on some machines.  Anyone know what it portends?

	>rpm -qf /usr/lib/rpm/debugedit
	rpm-build-4.11.2-2.fc20.x86_64

on both machines I've tried it on.
