You need to create the file jdk/src/solaris/bin/arm/jvm.cfg before
building.  The other platforms (zero included) have their own files
there.  Setting ZERO_BUILD=true enables some logic that causes the
file to be copied from jdk/src/solaris/bin/zero/jvm.cfg rather than
jdk/src/solaris/bin/$(ARCH)/jvm.cfg.
