It seems to happen whenever you try to build documentation for a
package that has a lot of build dependencies, and thus a lot of other
packages to link to.  This would be unusual for a package that was
part of the distribution.  My request would be that haddock be
compiled with -rtosopts enabled and that a way to pass haddock-options
be added to hlibrary.mk.  But it is not a blocker for me, I just
disabled the documentation deb for the package in question.
