Thanks for the swift reply Khem.  I commented out the line from
gcc-cross-candian.inc
#GCCMULTILIB = "--enable-multilib"

and tried
 --disable-multilib
in the EXTRA_OECONF

but I still get the same error when linking.  Let me know if there is
anything else I could try as I'm stumped.  Is there a workaround just
so I can get the developers up and running?

Cheers, Martin.
