small fix for makefile for building on linux

[Dalibor Topic]

hi,

the attached fix is a small fixlet that lets me use the makefile again 
for building javac.

the patch does three things:

* setting SRC_CLASSES to the relative path of the source directories, and

* setting ECHO to printf, as that's more useful for posixy systems (and 
avoids having the build fail due to a spurious -e in the javac.srcfiles 
file when using bash 3.2.17), and

* using BUILD_CLASSES as the location of properties on the classpath, 
rather than SRC_CLASSES, to avoid wasting time rebuilding the transitive 
closure of the class library used by javac (and adapting the makefile to 
deal with things like native or generated classes in that).

cheers,
