Ahh... yes, that was the problem. MPM_METHOD wasn't in Configuration.tmpl.
After adding it one can use configure as long as one disables a few modules
(they need ap_send_fb which seems to be kicked out):

$ ./configure \
  --disable-module=status" \
  --disable-module=include" \
  --disable-module=cgi" \

But the problem is that Rule's aren't intended to get a value other than
yes/no/default assigned, so it doesn't play nice with the existing config
stuff.  I suggest that we rename "Rule MPM_METHOD=default" to a variable
"MPM_METHOD=default" (which can then get any value assigned) and for enabling
the stuff we use a boolean "Rule MPM=default".  This way one can configure
apache-mpm for preforking via 

$ ./configure --enable-rule=MPM

or explicitly

$ MPM_METHOD=prefork ./configure --enable-rule=MPM

and for threading via:

$ MPM_METHOD=mpmt_pthread ./configure --enable-rule=MPM

I felt free to commit a change for this. Hope it is ok.
