I broke the distcheck target with this; good thing there were no need to
release yet.  I was thinking about ways to fix it, like copying instead
of linking, but I think the cleanest solution is to disable the
compilation of object files into subdirectories:

* configure.ac: Drop the subdir-objects Automake option, since it's
incompatible with picking source files from libatomic_ops.

This option is nice, but not really important for libgc, since most of
the sources are in the same directory.  Hopefully the last build fix for
now...
