I am not that sure... Our main target is DJGPP, that already implements
its own C library (and it does not implement libc as a shared
library...)

Did you try stripping it? Stripped binaries should not be too big (only
the needed parts of the libc are actually linked).

I think we should not confuse "application level" shared libraries
(DLLs) with "kernel level" drivers (modules). Currently, we support
dynamic linking for kernel drivers, and for DLLs if the PE format is
used. COFF does not support shared objects (I think), and ELF shared
objects are not supported yet. 

I am not particularly interested in shared libraries for COFF
executables (if DJGPP does not support them, I am happy without shared
libraries ;-) In my opinion, if you want a dynamic libc you should go
for a PE executable (since this solution should not require changes to
the kernel).
