automake: create compat symlinks only for linux systems

The primary users of these are linux developers, although
it can be extended for *BSD and others if needed.

Fixes make install for Cygwin and OpenBSD at least.

v2:
 - Wrap vdpau targets as well.
v3:
 - Fold HAVE_COMPAT_SYMLINKS conditional within install*links.mk
