When you said "brings aarch64-elf targets in line with other *-elf targets (x86_64-elf, riscv64-elf, etc.)", I hadn't realized that it was specifically the *-elf configs you were referring to and not just any aarch64 platform using ELF formats.  I now see we were already using this in aarch64linux.sh (and most of the others).

So this is OK.

Apologies for the confusion.
