The real problem is that the notice function in Cabal passes its argument to a function called wraptext, so when your package name gets very long a newline is inserted in the message that hlibrary.mk doesn't expect.

I encountered a failure whose origins are mysterious but which is fixable with the attached patch. There are a number of elements that combine to cause this bug:1. The Cabal library outputs most of its progress messages to stdout rather than stderr, which means that hlibrary.mk needs to filter them out2. The sed _expression_ that filters these messages out is not anchored, so it depends on some uncertain greedyness properties of the regex system3. The blank line left behind by the sed _expression_ is turning into a space at the beginning of the value assigned to pkg_config. Is this new? I don't know.I'm not sure which of these elements changed, but something did. I guess I'm not even sure about that. The symptom of this bug is messages like this:
