What should the replacement be? The Automake NEWS from git (unreleased) says:
- Use of the special makefile variable 'ACLOCAL_AMFLAGS' is deprecated.
To specify locations of extra m4 files, the 'AC_CONFIG_MACRO_DIR' or
'AC_CONFIG_MACRO_DIRS' (the latter introduced with autoconf 2.70)
should be used instead.
The Autoconf NEWS from git (unreleased) goes into more details:
- AC_CONFIG_MACRO_DIRS
New macro, used to declare multiple directories when looking for
local M4 macros. This macro overcomes some of the shortfalls in the
older AC_CONFIG_MACRO_DIR, which could only be used once; ...
The result of gnulib-tool most often contains a directory m4 files which
is not the only one for a given package. Therefore the recommended replacement
should be to use AC_CONFIG_MACRO_DIRS.
But AC_CONFIG_MACRO_DIRS is not yet released.

This is all welcome, but only after Autoconf 2.70 is released.
