installing glibc-2.1 as normal user

[Kasper Peeters <K.Peeters@damtp.cam.ac.uk>]

I am trying to install glibc-2.1 on a glibc-2.0 based machine as a
normal user (I am not root on this machine and the sysadmins do not
want modern stuff). 

This, apparently, leads to a problem. Even though glibc-2.1 can be
used to run glibc-2.0, it seems that you _have_ to use the 2.1 dynamic
loader ld-2.1.so. That is fine if I just want to run a binary, since I
can just do

   ~/lib/ld-2.1.so [programname]

and it will work. But it is annoying, and it also means that I cannot
use scripts which are started through `#!/bin/...' since 

   ~/lib/ld-2.1.so [script]

then has to be run as

   ~/lib/ld-2.1.so [interpreter] [script]

(the dynamic loader does not like scripts) and I have to figure out
the name of the interpreter myself by peeking at the script.


I guess I'm asking for the impossible here, but is there a way to
separate the _dl_* stuff in ld-2.1.so into a separate library such
that I can use the glibc-2.0 dynamic loader with the 2.1 libraries?
Or any other smart trick that makes the kernel use my glibc-2.1
dynamic loader instead of the /lib/ld-linux-2.so one?
