I have no idea why argv0 is NULL, but that's what I see. If you say it
shouldn't happen, then my patch should not cause any problem for you.

I tried to compile busybox with debug information so I could find out why argv0
is NULL, but compiler refuse to generate debug information although I've added
-g3 and -ggdb3 to the command line:
  arm-openwrt-linux-gnueabi-gcc -Wp,-MD,libbb/.procps.o.d   -std=gnu99
-Iinclude -Ilibbb  -include include/autoconf.h -D_GNU_SOURCE -DNDEBUG

-D"KBUILD_MODNAME=KBUILD_STR(procps)" -c -o libbb/procps.o libbb/procps.c

No matter what I do, gdb says that resulted libbb/procps.o contain no debug
information.
