Well, given the many incompatible changes, I'm sure distros will
continue to provide automake 1.x in some form for the foreseeable
future.

Not sure when those links were introduced.  We have Mesa 9.2.5 on
OpenBSD, but the build process is heavily custumized because the Mesa
build doesn't fit in with how we build Xorg on OpenBSD.  But I see
some evidence that these links are one of the reason why we have this
custom build process.  This makes it a serious effort for us to deal
with Mesa updates.  Please don't force us to do the same thing for the
xserver.

Getting real files is even worse.  That way you have multiple copies
of the same files and need to keep them in sync.
