The PKGDIR Makefile variable can be programmatically derived from
the PACKAGE variable, and it is universally so derived....
except in 2 Makefiles, where it is explicitly assigned,
for example,

 PACKAGE = com.sun.java.util.jar.pack
 PKGDIR = com/sun/java/util/jar/pack

But if you remove those PKGDIR assignments, the build fails!!
Why??

Ahhhh, it's those !@#$ trailing spaces on the PACKAGE assigment
(grrrrrr).

After removing the trailing spaces from all the PACKAGE assignments,
it is possible to remove all the PKGDIR assignments, except for the
generic one.

And the generic one can be improved in an obvious way,
removing two process creations and avoiding another chance
for SED to go wrong.
