Sorry, this doesn't actually work. We now have

http://autobuild.buildroot.net/results/1cca8b4115674f12884bcbc0c680efed0fb939ae/

Which is because poco now gets rebuilt at the install staging/target
steps, where we're not passing MYSQL_LIBDIR/INCDIR as all the .o targets
are considered out of date because of the phony objdirs prerequisite.

I don't right away see a clean solution to it (you could use order-only
('|') rules, but it isn't really pretty), so I simply reverted this and
just changed the build step to use MAKE1.

Feel free to submit a correct patch insted.
