Clean up makefile.

- Remove all:.  It's redundant, and ${LIB} in it is just a bug.
- Remove .ORDER:.  *.mgc files can safely be built in parallel.
- Remove PITA.  The mkmagic tool is smart to put the binary file
  into the current directory (${.OBJDIR}) even if the source file
  lives somewhere else, which is just what we need.
