Alexandre, thank you very much for the detailed explanation.  

Dear Guile maintainers: I have prepared the patch below, which checks
for Automake 1.4, for which the work-around is still used; for newer
automake, aclocal is called directly.  (Alternatively, one could
require Automake 1.5 for hacking Guile and get rid of the work-around
altogether.)
