There are several approaches to this problem:

1) Strip the shared libraries, if you have not already done that.

2) Statically link the executables you need and remove the shared libraries
altogether.
You might also investigate dietlibc, a C library you can link against
that is as slim as possible.

3) Use a kit like busybox that has alternative versions of many of the
commands you need and is optimized for small size.
