Subject: compiler: Drop --build-id=none hack

Since 2011 the object-joining implementation has had a hack to pass
`--build-id=none` to `ld` when supported, seemingly to work around a
linker bug. This hack is now unnecessary and may break downstream users
who expect objects to have valid build-ids. Remove it.

Closes #22060.
