Reduce glibc libraries...

Hello,
I have a problem to ask when applying embed-linux in our product. Since our application may need many share libraries when running,
and most of these libraries seem to be too large: libc.so.6 is about 1.5M, and the ld.so.1 is about 180K, and there are still other libraries...
If I put the linux kernel and root-fs in my flash(about 2M), I am
fear that there may be no enough space to hold all of them. So do I have to modify and remove any unuseful sources from the glibc libraries to reduce the size of libraries I need? But it is too difficult. So what's your suggestions or alternative methods ? Does it make any difference if I compile my application with static-link options "-s"? Are there someone to do these jobs now?
Thank you very much:-)
