compiling x86 busybox with uclibc support

Set Makefile CROSS_COMPILE variable to gcc which link with uclibc.
There are at least 3 possibilities to get such gcc.  
1) Build custom GNU toolchain
2) Use debian uclibc-toolchain wrapper
3) Create custom gcc wrapper

AFAIK Option 1) is a must if you plan to use floating point.
I use 3) option with below script but it's unreliable (I show it only
for reference)

#!/bin/sh

uclibc=/usr/src/uClibc-0.9.29
gccdir="/usr/lib/gcc-lib/i486-linux/3.3.5/"
gccinc="$/include"
gcclib="$"
lnxinc="/usr/src/linux-2.6.16.y/include/"

linking="yes"
static="no"
busybox="no"
for opt in $* ; do
        case $opt in
        -c|-S|-E) linking="no" ;;
        -static) static="yes" ;;
        busybox_unstripped) busybox="yes" ;; # FIXME
        esac
done

ldopts=
suffix=
if [ "$linking" == "yes" ] ; then
        ldir="$/lib/"
        if [ "$static" == "yes" ] ; then
                crt1=  
                if [ "$busybox" == "no" ] ; then
                        crt1="$/Scrt1.o"
                fi      
                ld_dyn=
                ld_libs="-L$ -lc -lgcc"

                suffix="$/libc.a $/libgcc.a"
        else
                crt1=  
                if [ "$busybox" == "no" ] ; then        
                        crt1="$/crt1.o"
                fi
                ld_dyn="-Wl,-rpath,$/lib,--dynamic-linker
$/lib/ld-uClibc.so"
                ld_libs="-L$ -lc -lgcc"
        fi
        ldopts="$ld_dyn $crt1 $ld_libs"
fi
incopts="-nostdinc -I$/include -I$lnxinc -isystem $gccinc"
libopts="-nostdlib -nodefaultlibs"

exec gcc $incopts $libopts $ldopts $* $suffix

hm, sound complicated...



unfortunately Im unable to backport the debian uclibc package for
debian etch.



Hm, this could probable be the way to go. All I need is a static
busybox binary after all.

What is an "debian etch" ?

Debian GNU/Linux 4.0 usually know by its codename "etch" :)
