Best solution is to fix `automake'.

Yep.  But, this loses relevant dependency information, and unless you do
a `make clean' too, you won't recompile files that need to be
recompiled.  I do

	rm -fr `find . -name .deps -print` && make clean && make

If you changed the compiler, even the fixed `automake' would have
recompiled all files anyway.
