Again, flexibility: for example gcc in its tree has things like
  ACLOCAL_AMFLAGS = -I ../config -I .. -I .

but its AC_CONFIG_MACRO_DIR is empty in some directories, and m4 or
../config in others.

Hmmyes, this sounds like a better default than what we have now.
After all, a user that needs to override it can still set
  ACLOCAL_AMFLAGS =
