 martin informs me that this is still happening.  i can't
 reproduce it myself today, but i've seen it occasionally
 in my many builds in the last few years.
 
 i had a look at the implementation, and after discussion
 with dholland we're wondering if this is a make(1) bug
 in the handling of a particular expression:
 
    GMAKE_J_ARGS?=  ${MAKEFLAGS:[*]:M*-j*:C/.*(-j ?[0-9]*).*/\1/W}
 
 which comes from tools/Makefile.gnuhost not properly
 removing the "-d" that build.sh adds here:
 
    MAKEFLAGS="-de -m ${TOP}/share/mk ${MAKEFLAGS}"
 
 the expression *should* only be capable of keeping the
 '-jN' or '-j N' parts in MAKEFLAGS, removing any other
 strings.
 
 i'm guessing above.  i wonder if something in the i386
 builds is tripping this.. but i have no idea what yet.
