“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!
Ludo’.
