I work with a few different unix systems and build binutils+gcc for
them. The AIX version I do this for is 6.1 TL06 SP09.
After I build binutils on AIX, I remove a few of the binaries because
they don't appear to properly work on AIX, though I do not have this
issue on Linux/HPUX/Solaris. These are: ar as ld nm ranlib strip. I
think that's probably most of the common tools for binutils, so maybe
try building gcc without binutils?
The most recent version I've done this for is gcc 8.3.0 and binutils
2.26. I was not able to get newer versions of binutils to build on my
AIX host at all, which is why it was not something more contemporary
with gcc 8.3.0. So my experience here may not matter if something is
different in gcc 9.3.0.
