You should not need to tell make to perform parallel build, this is  
handled already in the makefile, using "-j4" as default, see

Makefile.in:# the command line if needed. Also, need to specify  
PARALLEL_GNATMAKE_FLAGS
Makefile.in:PARALLEL_GNATMAKE_FLAGS = -j4
Makefile.in:BASE_GNATMAKE_FLAGS	  := ${ADAFLAGS} $ 
{PARALLEL_GNATMAKE_FLAGS} ${EXTRA_GNATMAKE_FLAGS}

The problem here is that make does not know how to build in parrallel  
correctly, whereas gnatmake does.
