d3e2f5ab99 Makefiles: Stop using $(SUBDIRS) 
This patch avoids that the following warning is reported when building
against kernel v4.21:

================= WARNING ================
'SUBDIRS' will be removed after Linux 5.3
Please use 'M=' or 'KBUILD_EXTMOD' instead
==========================================


A quote from an upstream kernel patch:

commit 07e5823127155b3a29003aca926f87c9843f6810
Author: Andrew Morton <akpm@osdl.org>
Date:   Mon Apr 12 01:05:40 2004 -0700

    [PATCH] kbuild: external module support
    
    From: Sam Ravnborg <sam@ravnborg.org>
    
    Based on initial patch from Andreas Gruenbacher there is now better support
    for building external modules with kbuild.
    
    The preferred syntax is now:
    make -C $KERNELSRC M=$PWD
    
    but the old syntax:
    make -C $KERNELSRC SUBDIRS=$PWD modules
    will remain supported.

ec73c01358 scst_local: Use all CPUs for command processing 
This patch modifies scst_local such that on kernel version 3.19 and
later multiple hardware queues are used (scsi-mq). Note: in order
to benefit from concurrent processing, the number of SCST command
threads must be set to a value above one.

4ac6d7a26d [PATCH] scst: Drop detect() method 
There is no need for a detect() method - code that is present in such
a method can be moved to module_init(). Hence declare this method
obsolete. Leave the detect pointer member in the target template for
now for out-of-tree SCST drivers.
