Wow, this is really weird! There is a file
openjdk-ecj/jdk/make/common/shared/Defs-utils.gmk containing all the
tool variable definitions - including UNZIP. So I removed the
EXTRA_OEMAKE part for UNZIP and added the path to our native unzip
executable directly into Defs-utils.gmk and guess what. That works!

This is really weird because the 'Unzipper' command actually echos its
arguments and there $2 is printed perfectly. But when it is accessed a
second time in the actual call it is wrong.

/me puzzled ....
