Hm, now in a "make rpm" build which has source in one place and rpm build
area in another:

/bin/ln: creating hard link `/home/sandeen/rpmbuild/BUILDROOT/e2fsprogs-1.41.14-0.x86_64/usr/include/com_err.h' => `/usr/include/et/com_err.h': Invalid cross-device link

so I'm not quite sure how to work around this.

Maybe in the end it does have to be packaging-specific, with the
link created by the distro pkg scripts...?
