 If you add this to the Makefile in every subdirectory (this is for
 netgraph, for each directory please replace the string netgraph
 with the name of the current directory):
 
  .if ${MACHINE_ARCH} == "i386"
  # Things that don't compile on alpha or are aout specific:
  SUBDIR+= bluetooth
  .endif
  
 +CURDIR:=${.CURDIR:C/^.*\/modules\///}
 +.for d in ${SUBDIR}
 +.if ${WITHOUT_MODULES:Mnetgraph/${d}}!=""
 +SUBDIR:= ${SUBDIR:N${d}}
 +.endif
 +.endfor
  
  .include <bsd.subdir.mk>
 
 you can do:
 
 WITHOUT_MODULES= netgraph/one2many syscons/fire
 
 and then the modules netgraph/one2man and syscons/fire are ignored,
 while the rest is happily made.
