I don't know, by heart. You could give it a try, if you want.
Just download rubyscript2exe.tar.gz and change this line in
ev/dependencies.rb:

 OLD: def ldds(file, notthedefaults=true)
 NEW: def ldds(file, notthedefaults=false)

"Compile" your application with: ruby init.rb test.rb

This will copy all dependencies, instead of excluding the files
which are supposed to exist on every Linux system. I can't
predict how the "wrong" libc combines with the kernel. Could be
tricky...

Please let me know the results.

PS: Excluded files are: libX11.so.6, libXt.so.6, libGL.so.1,
    libXext.so.6, libICE.so.6, libSM.so.6, libdl.so.2,
    libcrypt.so.1, libz.so.1, libncurses.so.5, libutil.so.1,
    libpthread.so.0, libpam.so.0, libgcc_s.so.1, libm.so.6,
    libdl.so.2, libcrypt.so.1, libc.so.6, libpthread.so.0 and
    ld-lsb.so.1.
