https://en.wikipedia.org/wiki/Minix_3:

"2013-02-21 ... Dropped support for a.out binaries"

They themselves killed that support a lot earlier. :-)

Good question.

Unfortunately, I'm just the janitor removing this and a.out is waaay
before my time. :-)

But I'm open to suggestions on how to determine which are those obsolete
syscalls.

Btw, pls do note that this is removing only the x86 a.out support -
other arches (m68k and alpha) still select HAVE_AOUT and thus the
respective glue in fs/binfmt_aout.c
