generating AC_OUTPUT list in configure.in

Is there a way to write "configure.in" such that I just give the list of 
subdirs, then
AC_OUTPUT() will be filled with subdir/Makefile.

My intension in the following (which does not work ;-) )

   subdirs="dir1 dir2 dir3"
   outfiles=""
   for var in $subdirs
   do
      outfiles="$outfiles $var/Makefile"
   done
   AC_OUTPUT($outfiles)       

I have so many subdirs and thus I'm getting sich of adding "/Makefile".

Thank you.
