Those platforms moved away from the .gnu_debuglink approach to use
build-id instead. See (info "(gdb) Separate Debug Files")
I don't really recall how .gnu_debuglink works, but I am somewhat
surprised to hear it should be in the separate debug file. My
understanding of it was that it recorded a CRC and the verification
happened by computing the CRC of the separate debug file (this is
expensive, which is why build-id is superior...).
So I suppose this is just a bug but the cause remains unknown.
