I've already written about the possibility of creating an ebuild to simply _replace_ the entire buildsystem of a package if it's non-existant (simple .c file thrown around by upstream), too minimal and/or impossible to get upstream do adapt, or as a temporary measure until upstream is beaten into common sense.
The whole story can be found at http://blog.flameeyes.eu/2008/10/15/fixing-cflags-ldflags-handling-with-a-single-boilerplate-makefile I'm attaching a proof of concept of the eclass, it's certainly not ready for prime time: it does not support C++ programs, it does not have pkg-config support, and so on. But in general it should work, I'm also attaching a reworked ebuild for uif2iso (package I maintain and for which I had to _rewrite_ the whole Makefile already). This gets especially interesting to consider if we want to enable --as-needed by default, since this will allow easy fix for packages that don't otherwise build with --as-needed, like habak that I had to fix, and takes care of quite a few different problems at once.
