[PATCH] Add --enable-locallisppath option to configure.in

["Jérôme Marant" <jmarant@free.fr>]

Hi,

Currently, only the configure script generates epaths, by calling the
'epaths-force' target of the Makefile.

However, it is not possible to customize the value of the
locallisppath variable in order to include it in epaths at
configure-time, which makes necessary to re-run 'make epaths-force'
with a customized locallisppath.

The following patch adds a --enable-locallisppath option for this
purpose. It attemps to follow the --enable-* options semantic:

  --enable-locallisppath, --enable-locallisppath=yes: leaves the default value

  --disable-locallisppath, --enable-locallisppath=no: removes locallisppath
    from lisppath

  --enable-locallisppath=PATH: set locallisppath and adds it to lisppath

Cheers,
