[PATCH] Allow to disable CONFIG_SCSI_WAIT_SCAN=m in menuconfig.

[Clemens Koller <clemens.koller@anagramm.de>]

Hi there!

This was already discussed in May: http://lkml.org/lkml/2007/5/13/75
without any valuable results.

I don't want to have the scsi_wait_scan.ko around but still need
SCSI for usb disks and module support for driver development.
Otherwise, I am working with a monolithic kernel on embedded machines.

The attached patch is another try to at least allow to get
rid of this module.

Feedback is welcome.

Regards,

Allow to disable to build the scsi_wait_scan.ko module if not needed.
