Why is this ld directive needed?  They don't use it in Nix, for
instance.  A comment would be helpful.

Looking at the Nix package definition, they do some other things that we
don't have, which we perhaps should:

--8<---------------cut here---------------start------------->8---
  postPatch = ''
    substituteInPlace eeprom/decode-edid \
      --replace "/usr/sbin/parse-edid" "${read-edid}/bin/parse-edid"

    substituteInPlace stub/i2c-stub-from-dump \
      --replace "/sbin/" ""
;--8<---------------cut here---------------end--------------->8---

They patch a reference to parse-edid and strip the '/sbin/' prefix from
some other place.

The rest LGTM!
