Subject: Make sure the user doesn't have any stray files from previous
 attempts to compile aureal in their kernel statically (yes, having them there
 does break the aureal module).  Modularize the makefile using SRCPREFIX,
 which can be changed in the environment.

Approved in principle by:	maintainer (except SRCPREFIX)
