Well, it must :), otherwise building it is quite probably impossible,
as it seems that GNU binutils do not fully support AIX - but I can't
say for sure, as I were unable to find a definite list of supported
systems. I tried building using GNU binutils, but 'as' refused to
compile source code, claiming that it does not know about instruction
fmul, if my memory serves well.
Hard to say what the GNU binutils really support or not but trying them
is always possible. So I tried the binutils-2.20.51 :
[root@localhost build]# rs6000-ibm-aix4.3-as --version

This assembler was configured for a target of `rs6000-ibm-aix4.3'.
and then gcc-4.6.2. Of course it crashed during the libgcc build :

when I hadn't those AIX 4.3 target headers :-( My configure options
can be seen in the following :
[root@localhost build]# gcc/xgcc -v
Using built-in specs.
COLLECT_GCC=gcc/xgcc
Target: rs6000-ibm-aix4.3
Configured with: ../configure --build=i686-linux-gnu
--host=i686-linux-gnu --target=rs6000-ibm-aix4.3 --with-gnu-as
--with-gnu-ld --enable-languages=c,c++ --disable-threads --disable-nls
Thread model: aix
gcc version 4.6.2 (GCC)
The '--disable-threads' didn't seem to have any influence!
The 'gmp', 'mpfr' and 'mpc' sources were built with the gcc-4.6.2
sources...
Are the AIX 4.3 etc C-libraries freely available somewhere nowadays?
Years ago I tried to find them but then IBM hadn't put them freely
available like SGI with Irix stuff and Sun with Solaris2 stuff :-(
