 OK.  Zack Weinberg applied a patch which does a similar
 thing to subdirs:
 http://subversions.gnu.org/cgi-bin/viewcvs/gcc/gcc/gcc/configure.in.diff?r1=text&tr1=1.573&r2=text&tr2=1.574&diff_format=u
 
 and:
 http://subversions.gnu.org/cgi-bin/viewcvs/gcc/gcc/gcc/configure.diff?r1=text&tr1=1.583&r2=text&tr2=1.584&diff_format=u
 
 So maybe that is the right thing to do here?
 
 Edwin, can you try changing your fix to:
 subdirs='$subdirs'
 
 and see if that works?
