I can reproduce it.

AFAICS using "make V=1" we fail only to add the correct "ELC+ELN" in
place of "ELC" but we invoke the right command, will try to have a look.

Regarding the macro expansion issue I tried to have a quick look but I'm
not very much into cl-generic.el and couldn't spot any obvious (for me)
issue so far.
