Stupid me.
Yes, in Makefiles, one must use a .SUFFIXES target.
But in Makefile.am files, one must use a SUFFIXES variable!
And then, automake generates a .SUFFIXES target from the content 
of the SUFFIXES variable defined in Makefile.am files.

As a consequence, this is correct in a Makefile, but wrong in a 
.SUFFIXES: .erl .beam .rel .script .boot

And in a Makefile.am, one should really write:
SUFFIXES = .erl .beam .rel .script .boot

Sorry for the confusion.
