[TRIVIAL] fix parallel builds for aic7xxx]

[Rusty Trivial Russell <trivial@rustcorp.com.au>]

[ Sorry, did you guys end up with consensus on this?  Should I forward
  or drop?  Thanks, Rusty ]

From:  John Cherry <cherry@osdl.org>

  My compile regression scripts were getting random build failures for
  aic7xxx.  The two makefiles could not handle parallel build. 
  Occasionally they would succeed...timing dependent.  The following two
  patches fix this.
  
  Part 1 - drivers/scsi/aic7xxx/Makefile
  Part 2 - drivers/scsi/aic7xxx/aicasm/Makefile
