I've been trying to find an elegant way to do this for months,
in which elegant is liberally defined as a Perl script under 1000
lines.  This script is about 30 of actual code, thus fits into
the normal definition of elegant.

Basically, you run 'libstrip busybox', and it will relink the
uClibc shared object file containing only the symbols necessary
to fully resolve busybox (or any other executable on the command
line.)

Results:
  libuClibc.so, unlibstripped:                           139864
  libuClibc.so, libstripped for default busybox config:   99668
  libuClibc.so, libstripped for test/*:                   11668 [1]

By the way, 139864 is a result of using  OPTIMIZATION = -Os
-mpreferred-stack-boundary=2 -malign-loops=0 -malign-jumps=0
-malign-functions=0.  That seems to be the best in terms of
size.

test programs.
