Hi,

Do you have figures before and after the change?

The reason I’m asking is that (gnu packages commencement) arranges to
not call ‘make-ld-wrapper’ repeatedly already.  For instance, there’s:

  (define-public ld-wrapper
    ;; The final 'ld' wrapper, which uses the final Guile and Binutils.
    (make-ld-wrapper "ld-wrapper"
                     #:binutils binutils-final
                     #:guile guile-final
                     #:bash bash-final))

and from there on we manipulate a single <package> record.

Thanks,
Ludo’.
