So what do you do with
  --bindir=/foo --with-layout=bar --sbindir=/baz

shouldn't the bar layout override bindir but not sbindir?  (Note I don't
know the exact semantics --with-layout is supposed to have.)

BTW, all of the apr_common.m4 code and your .in files anyway need an
audit pass to cope with the GCS-induced changes for --datarootdir and
its consequences; see the Autoconf NEWS entries and the manual about
the changed default directories (and new ones).

Cheers,
Ralf
