The selection of the X.org server type was really strange. The user
had to select between none, tinyx and modular. Now, the menuconfig
interface display a single item for X.org, that can be
selected/unselected. This entry contains a submenu, that allows to
select the type of the X.org server (tinyX or modular) and that allows
(as before) to enable/disable X.org libraries, drivers, etc.
