Bart Van Assche 33f2f4a064 Makefiles: Only read the build_mode file if building inside the SCST tree 
This patch avoids that the build_mode file is read when applying the
generate-kernel-patch output to the kernel tree and when building the
kernel tree.

archive, only support in-tree builds with $(SCST_INC_DIR) and $(SCST_DIR).

Bart Van Assche 08e532715d Remove procfs support 
Since all RHEL/CentOS 5 users have upgraded to a newer version, procfs
support is no longer necessary. Hence remove procfs support. This patch
has been generated as follows:

git grep -lw CONFIG_SCST_PROC iscsi-scst qla2x00t scst scst_local srpt |\
  while read f; do
    echo ${f}
    unifdef -U CONFIG_SCST_PROC ${f} >${f}.out
    mv ${f}.out ${f}
  done

followed by two small manual edits in scst/include/scst.h and also in
qla2x00t/qla2x00-target/qla2x00t.c.

This patch avoids that the following warning is reported when building

================= 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.
