Presumably the true "authoritative" source is an ARM document, but I don't have
that handy.
For binutils, the defines are in include/elf/common.h:
https://sourceware.org/git/?p=binutils-gdb.git;a=blob_plain;f=include/elf/common.h;hb=HEAD
The upstream kernel is also lacking the defines, as they're part of the ARM
patch set that is still in flight. The defines are still not present in glibc
as of today.
