The "tooldir" part tells the guessed, given or somehow else got $target 
name being 'powerpc-ibm-aix'...
But the 'gcc/config.gcc' doesn't know this $target :(  Possible ones can 
be '*-*-aix4*' and '*-*-aix5*'
where the first star can be 'rs6000', 'powerpc' or 'ppc'. So that bare 
'aix' isn't understood....

Please see what the command :
    ./config.guess
gives in the main GCC source directory. There shouldn't be that bare 
'aix' in the answer to the guess!
If there is (The system is really stupid in its guesses...), then you 
must be wiser and tell the right names,
for instance :
..../configure --build=powerpc-ibm-aix5.3 --host=powerpc-ibm-aix5.3 
--target=powerpc-ibm-aix5.3 ....
