[PATCH 0/4] Fixing dtrace object generation

[Peter Hutterer]

[PATCH 1.12] was the trigger for this series, I want that on the 1.12 branch
but for master the patch series applies.

We've disabled a bunch of tests when building with --disable-xorg but most
of those don't actually need Xorg to be built - libtool just doesn't package
up dix.O and os.O into libxservertest.la. Patch 3/4 changes from a custom
library that links all objects into dix.O to just using libtool to create a
.lo for the dtrace parts. Not sure how permissible this is though, review
very welcome.

Passes make dist on my box, but I definitely want XQuartz testing for this
too.

Cheers,
  Peter
