hush/Makefile
Eric Andersen 14d354312a Per suggestion from Vladimir, eliminate check_wildcard_match(), which 
was only being used by insmod these days.

Also, I spent a minute adjusting insmod so that it first searches
/lib/modules/`uname -r` and then (if that fails) searches /lib/modules,
which makes bb insmod behave much more like the real insmod, and should
avoid nasty surprises (such as the recent "Modutils vs. Busybox..."
thread).

# With a modern GNU make(1) (highly recommended, that's what all the
# developers use), all of the following configuration values can be
# overridden at the command line. For example:
# make CROSS=powerpc-linux- BB_SRC_DIR=$HOME/busybox PREFIX=/mnt/app
# If you want to add some simple compiler switches (like -march=i686),
# especially from the command line, use this instead of CFLAGS directly.
# For optimization overrides, it's better still to set OPTIMIZATION.

# If you want a static binary, turn this on.
DOSTATIC = false
# Set the following to `true' to make a debuggable build.
# Leave this set to `false' for production use.
# eg: `make DODEBUG=true tests'
# Do not enable this for production builds...
DODEBUG = false
# Setting this to `true' will cause busybox to directly use the system's
# password and group functions. Assuming you use GNU libc, when this is
# `true', you will need to install the /etc/nsswitch.conf configuration file
# and the required libnss_* libraries. This generally makes your embedded
# system quite a bit larger... If you leave this off, busybox will directly use
# the /etc/password, /etc/group files (and your system will be smaller, and I
# will get fewer emails asking about how glibc NSS works). Enabling this adds
# just 1.4k to the binary size (which is a _lot_ less then glibc NSS costs).
# Note that if you want hostname resolution to work with glibc, you still need
# the libnss_* libraries. Most people will want to leave this set to false.
USE_SYSTEM_PWD_GRP = true
# This enables compiling with dmalloc ( http://dmalloc.com/ )
# which is an excellent public domain mem leak and malloc problem
# detector. To enable dmalloc, before running busybox you will
# want to first set up your environment.
# eg: `export DMALLOC_OPTIONS=debug=0x14f47d83,inter=100,log=logfile`
# Do not enable this for production builds...
DODMALLOC = false
# Electric-fence is another very useful malloc debugging library.
# Do not enable this for production builds...
DOEFENCE = false
# If you want large file summit support, turn this on.
# This has no effect if you don't have a kernel with lfs
# support, and a system with libc-2.1.3 or later.
# Some of the programs that can benefit from lfs support
# are dd, gzip, mount, tar, and mkfs_minix.
# LFS allows you to use the above programs for files
# larger than 2GB!

# We need to set APPLET_SOURCES to something like
# $(shell busybox.sh Config.h)
# but in a manner that works with VPATH and BB_SRC_DIR.
# Possible ways to approach this:
#
# 1. Explicitly search through .:$(VPATH) for busybox.sh and config.h,
# then $(shell $(BUSYBOX_SH) $(CONFIG_H) $(BB_SRC_DIR))
#
# 2. Explicity search through .:$(VPATH) for slist.mk,
# then $(shell $(MAKE) -f $(SLIST_MK) VPATH=$(VPATH) BB_SRC_DIR=$(BB_SRC_DIR))
#
# 3. Create slist.mk in this directory, with commands embedded in
# a $(shell ...) command, and $(MAKE) it immediately.
#
# 4. Use a real rule within this makefile to create a file that sets
# APPLET_SOURCE_LIST, then include that file. Has complications
# with the first trip through the makefile (before processing the
# include) trying to do too much, and a spurious warning the first
# time make is run.
#
# This is option 3:
#
#APPLET_SOURCES = $(shell \
# echo -e 'all: busybox.sh Config.h\n\t@ $$(SHELL) $$^ $$(BB_SRC_DIR)' >slist.mk; \
# make -f slist.mk VPATH=$(VPATH) BB_SRC_DIR=$(BB_SRC_DIR) \
