autotools: don't try and find in-tree macros

autotools has improved a lot since this class was written, and there's
now no need to search the source tree for m4 files and add them to the
include path.

If packages have macros in subdirectories the idiom is to tell aclocal
via an assignment in Makefile.am:

  ACLOCAL_AMFLAGS = -I gl/m4 -I m4

If, for example, a package isn't autoreconfable out of the box (because
it has a non-trivial autogen.sh or similar, say) then the required -I
statements can be added to EXTRA_AUTORECONF.
