From: Emil Velikov <emmil.velikov at collabora.com>

Atm the actual rule will expand to foo.o which is used for static
libraries only.

Thus the automake manual recommendation [to use OBJEXT] won't help us,
since since we're working with a shared library.

Thus let's 'demote' the file and add it back to BUILT_SOURCES. This will
manage all the complexity for us, at the (existing expense) of working
only with the all, check and install targets.

The crazy (why the issue was hard to spot):
If the dependencies (.deps/*.Plo) are already created one can alter the
anv_device.$(OBJEXT) line and/or nuke it all together. That won't lead
to any warnings/issues, even though the Makefile is regenerated.

Moral of the story:
Always rm -rf top_builddir or don't resolve the dependencies manually
and use BUILT_SOURCES.

Just checking if make distcheck will find any fall-outs, but should work
like a charm.
