 Sounds familiar... Did this come from some assembler source file in 
'config/rs6000'?  I haven't the sources now, must boot Linux first to see...

 No, now I remember, the '-maix64' option in the MULTILIB-definitions causes 
this, it knows the '-a', '-i' and the '-x', but don't know the '-6' option.
I think that I mentioned that this must be taken away... Hmmm...

 Just remove the requirement to produce 'libgcc.a' using the '-maix64' option.
The things in:

----------------- clip ------------------------
MULTILIB_OPTIONS	= msoft-float \
     mcpu=common/mcpu=power/mcpu=powerpc/maix64

MULTILIB_DIRNAMES	= soft-float \
     common power powerpc aix64

MULTILIB_MATCHES	= msoft-float=mcpu?403 \
     maix64=maix64 \
     mcpu?power=mpower \
     mcpu?power=mrios1 \
     mcpu?power=mcpu?rios1 \
     mcpu?power=mcpu?rsc \
     mcpu?power=mcpu?rsc1 \
     mcpu?power=mpower2 \
----------------- clip ------------------------

must be changed into:

----------------- clip ------------------------
MULTILIB_OPTIONS	= msoft-float \
     mcpu=common/mcpu=power/mcpu=powerpc

MULTILIB_DIRNAMES	= soft-float \
     common power powerpc

MULTILIB_MATCHES	= msoft-float=mcpu?403 \
     mcpu?power=mpower \
     mcpu?power=mrios1 \
     mcpu?power=mcpu?rios1 \
     mcpu?power=mcpu?rsc \
     mcpu?power=mcpu?rsc1 \
     mcpu?power=mpower2 \
----------------- clip ------------------------
