Yes, at least for most of them (e.g. SPARC psABI specifies exactly the two
values you see here).
If you wanted to change the default, you'd either have to come up with a new target
(elf32freebsd_i386 or whatever) or identify FreeBSD ABI binaries (e.g. with
.note.ABI-tag), read that and do something what elf32-mips already does in
ELF_DYNAMIC_INTERPRETER for different ABI binaries.
But IMHO you really should teach all your compilers to invoke ld properly
and if somebody is doing final link of dynamically linked executables with
ld by hand, he should roll his own.
