kbuild: Compatible with old bash, fix help, make clean fix

From: Sam Ravnborg (sam@ravnborg.org)
Date: Sun Nov 03 2002 - 13:46:54 EST


AWK exported now, as pointed out by Keith.

kbuild fixes:
o Do not use "-" in exported symbols, bash does not support that (Matthew/Keith)
o Sort ALL_SUBDIRS, to avoid warning about duplicate target
        - Happens when the same directory are specified with drivers-y
          and drivers-n
o Added AWK, a few architectures actually use awk for normal compilation
o Removed distclean from make help, now that distclean and mrporper are merged
