Then let's try it on a few packages. I'll try on some of mine and give
you feedback.

Maybe it should do that on all GNU systems, they should all have a
correct linker (dunno for BSD).

I don't know what happens when you don't put that stuff in the .la.
Shouldn't it still be used when linking statically ?

Even if we're probably going to have some issues with it, I hardly see
how it could be more broken than the current behaviour.

I guess that patch has to be applied before running autoconf, or else it
won't be very useful.
