hi,

dchagin# file /compat/linux/sbin/ldconfig
/compat/linux/sbin/ldconfig: ELF 32-bit LSB executable, Intel 80386,
version 1 (GNU/Linux), statically linked, for GNU/Linux 2.6.9, stripped

dchagin# brandelf -f 0 /compat/linux/sbin/ldconfig

dchagin# /compat/linux/sbin/ldconfig -V
ldconfig (GNU libc) 2.7

dchagin# readelf -h /compat/linux/sbin/ldconfig | grep ABI
  OS/ABI:                            UNIX - System V
  ABI Version:                       0
dchagin#

so it works for statically linked binaries also.
Unfortunately, I not the best person for a documentation
writing... Therefore I will make it a bit later :)
