I would rather remove all AOUT support.  AOUT as a format has been
obsolete since the advent of ELF in the 1990s.  See for example
J. Arnold "ELF: An Object File to Mitigate Mischievous Misoneism", In
Proc. of the Summer USENIX Conference, 1990.
COFF should have died too..

The sparc target obsolescence happened here:
https://sourceware.org/ml/binutils/2016-09/msg00184.html

You've had quite a bit of warning, but I guess you just built binutils
with --enable-obsolete, or stayed with older binutils.  Well, older
binutils are likely to be better for AOUT anyway.  So what's to
prevent you using older binutils for sparc-aout?
