* Drivers.macros (AC_DRIVER_ALIAS): Remove definition. (AC_DRIVER): Extend to take a `description' parameter and consider `$enable_default_device_drivers'. (AC_DRIVER_nodef): New definition. * configure.in (options kdb, kmsg): Remove redundancy. * i386/configure.in (option default-device-drivers): New option. (option lpr): Consider `$enable_default_device_drivers'. * i386/linux/configure.ac: Rework substantially. Remove all aliases. Rename some of the device driver options. (option default-device-drivers): New option. (linux_DRIVER): Take care about a `description' parameter and don't invoke AC_DRIVER_ALIAS. (linux_DRIVER_nodef): New definition. Adopt all usages of AC_DRIVER and linux_DRIVER to provide a `description' parameter. (g_NCR5380, NCR53c406a, eata_dma, wavelan, atp): Change from AC_DRIVER to AC_DRIVER_nodef to have these device drivers disabled by default. * doc/mach.texi: Add a note about the outdatedness to the configuration option table. * i386/README-Drivers: Update.
