[PATCH weston 11/11] configure: add an option to allow building only the libraries

[Giulio Camuffo]

the --enable/disable-weston-binaries enables or disables the creation
of 'weston', 'weston-launch' and all the binaries that are
installed in $prefix/lib/libexec. This allows, together with
--enable-clients, to only build the libraries, making possible to
build and install different libweston versions at the same time.
