I managed to build GraphicsMagick under FreeBSD with plain '-j'. 
Under Solaris the load factor went up to at least 167.58 but the build 
did succeed without problems.  GraphicsMagick uses a non-recursive 
build.  It does not use SUBDIRS.  SUBDIRS is broken for massive 
parallel make, or builds with just a source file or two per directory 
and a more mild parallel make.

Apparently the GNU make for Darwin has bugs.
