How to genetare multi libgcc

["Franzi Edo." <edo dot franzi at ukos dot ch>]

Hi,
Can someone help me for finding the right configuration for a 68k and  
CondFire toolchain?
Here is my problem:
I need to have a compiler capable to generate fpic code (code accesses  
by %PC, and data accesses by %A5).
The problem appears when I use float numbers. In this case, the  
compiler links my program with
../gcc-4.2.4/m68k-elf/lib/gcc/m68k-elf/4.2.4/m528x/libgcc.a(_float.o).  
So, the analysis of the generated code shows
that this libgcc.a doesn't contain any fpic code, so, my program  
crashes.
For a long time I have been using the gcc version 4.2.3 without any  
problems, now I have moved to the 4.2.4 (and I tried also the 4.3.1)
but this problem appears.
If I resume, it seems that for the version 4.2.3 the toolchain  
generates all the possible libgcc, but this is not the
case for the most recent versions (4.2.4 and 4.3.1).
Questions,:
1. how to modify my toolchain for making possible the generation of a  
multi libgcc (the normal and the fpic one)?
2. from the makefile how do I have to proceed for informing the linker  
to use one or the other library?
Thanks
  Edo

PS: here is my toolchain for generating the compiler (the 68k  
generates also for ColdFire)

#!/bin/sh
# usage: toolchain [m68k, arm, bfin] [gcc version]
# ex.    sh toolchain m68k 4.2.4
