So does TARGET identify the target platform and does BUILD_DIR identify 
the name of the directory (in this case .../LINUXLIBC6/ ) into which all 
the derived files should go?  Could BUILD_DIR be overridden?  That would 
suffice.  I'd just pick a different BUILD_DIR when I compile on one of y 
systems.

Every now and them Adobe Flash just stops working altogether on my 
system.
