This was the "GCC build" still in 'gcc-2.8.1', 'libiberty', 'libstdc++'

Nowadays it seems to hard to believe that the subdirectory "gcc" is what
should be called as "GCC",
the rest being "extra", produced after "GCC is ready"! Although the
directory name itself is the clue.
Anyway "make all-gcc ; make install-gcc' builds and installs "only
GCC". After that it is possible to
test how well the new compiler works, for instance by compiling and
linking the "Hello World". If
this doesn't work, it is quite vain to try 'libiberty' and 'libstdc++'
yet. But one should fix the headers,
libraries etc. so that producing simple executables will work. The
libiberty and libstdc++-v3 configure
system tries compiling and linking some simple apps when investigating
the target C library
As far as the "system headers", I basically copied /usr/include from
the AIX host and put it into /Users/pedz/Projects/aix-roots/5.3 and
then I set --with-sysroot equal to the base of that. I had to fix a
few symbolic links after the copy. As far as I know, that is all the
headers that gcc needs but I'm not sure.
Trying a "Hello World" with the "preliminary" GCC without libiberty and
libstdc++ yet, would tell
something about the situation.... The '$target/libiberty/config.log'
or the '$target/libstdc++-v3/config.log'
will tell what happened during the configure in question, where it
failed....
