configure.in loses with autoconf 2.59

The `extrasub' variable used in configure is undocumented.  Using it
(a) appears to have no effect on the Makefiles generated (b) loses
with autoconf 2.59.  The lossage involves messages like this from

  sed: -e expression #1, char 16: Extra characters after command
  bash: srcdir: command not found

due to it running a shell command of the form

  sed "... $(srcdir) ..."

        * configure.in: Don't use `extrasub'.
