# Icedtea's makefile is not compatible to parallelization so we cannot allow
# passing a valid ${PARALLEL_MAKE} to it. OTOH OpenJDK's makefiles are
# parallelizable and we need ${PARALLEL_MAKE} to derive the proper value.
# The base for this quirk is that GNU Make only considers the last "-j" option.
