Linker FP error with GNU 4.1.1

I have just upgraded from 3.3? to 4.1.1 and I get the following error on
linking

ERROR: main.o uses software FP, whereas  TT.elf use hardware FP

This applies to all modules.  The processor is lLPC2368 which doesn't
support hardware floating point.  How do I tell the linker this?  I have
tried the GNU manuals but I can't find any options.

Any help would be appreciated.
