“Everything” depends on ‘ld-wrapper’ (see commencement.scm), so you have
to come up with changes that do not modify the default ‘ld-wrapper’.

In these two cases, you’re changing the generated code from:

  (string-append bin "/" … "-ld")
  (string-append bin "/ld")

to:

  (string-append bin "/" … "-" "ld")
  (string-append bin "/" "ld")

To avoid a rebuild, you’ll have to special-case “ld” such that the
generated code is unchanged.

HTH!
