gdb-6.6, faking a shared library

- Subject: gdb-6.6, faking a shared library
I've got an arm program which makes use of a non-standard shared
library and I'm looking for ways to inform gdb that it really is a
shared library.
What I'm calling a shared library is a subset of glibc which gets
linked/mapped to a specific address, and the programs which "link
against it" really link against fixed addresses, thus no dynamic
linking is involved. Special startup code is used to map the library's
addresses for each process which need it. However, since gdb knows
nothing about it being shared among other processes (not simply other
pthreads sharing the same memory map), bad things happen when a
breakpoint in that library is hit by another process.
Any ideas for making gdb think that a certain address range is a shared
library? My glibc (v2.2.3) is NOT built for pic/dynamic linking. Thus
no libthread_db is built. Compiler is gcc v3.4.3, linux is 2.6.10 for
ARM.
Thanks, John
