As I've understood it this kind of problem is caused by the fine
details of how the linkers work. Basically they process one library at
a time but only pick up the symbols they need just then. If a later
library introduces a dependency on something in an earlier library
that wasn't already picked up it won't revisit that library
automatically. That's why extract_fuseki has duplicate libraries
listed in LD_ADD. Presumably the same trick should work for
mkmcpat. Try to add another copy of libengine.a at the end of the
mkmcpat_LDADD line instead of adding globals.c as a source file. I'm
not sure whether it's a technically better solution but it would at
least be more consistent.

What I don't understand is why the OS X linker is more picky with this
than the GNU linker.
