If it was only libc4 and libc5 that used the uselib system call then it can probably be removed after enough time.Only libc4 used it, libc5 was already ELF.binfmt_elf.c supports uselib. In a very a.out ish way. Do you know if that support was ever used? If we are truly talking a.out only we should be able to make uselib conditional on a.out support in the kernel which is strongly mostly disabled at this point.
The only ones that even allow setting AOUT: arch/alpha/Kconfig: select HAVE_AOUT arch/m68k/Kconfig: select HAVE_AOUT if MMU and x86 deprecated it March 2019: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=eac616557050737a8d6ef6fe0322d0980ff0ffde Christian
