[PATCH] libfortran: Simplify Makefile logic

Hi,

I think they don’t matter, but my automake skills are not that great, so I kept the current order.

Another improvement I could imagine is, instead of listing files explicitly, we could use some patterns/globing; but I don’t know how well it would work, how to achieve it, and whether it’s considered good practice in gcc’s build machinery generally.

I aimed to solve the existing problems, but with minimal disruption.

Patch pushed, thanks for the review.
