> Cannot handle 8-byte build ID

An 8-byte (just 64bits) build ID doesn't make much sense.
It is too small to make sure it is a globally unique identifier.
You need 16 bytes (128 bits) minimum.

This must be a linker bug. Older lld had a bug where they had a "fast" build-id
generator that produced such small (useless) build-ids.
