In (info "(autoconf) autoreconf Invocation")
there is:

    If you want `autoreconf' to pass flags that are not listed here on
 to `aclocal', set `ACLOCAL_AMFLAGS' in your `Makefile.am'.  Due to a
 limitation in the Autoconf implementation these flags currently must be
 set on a single line in `Makefile.am', without any backslash-newlines.

so if you use autoreconf (which is Recommended) in the bootstrap flow,
you can try adding

 ACLOCAL_AMFLAGS = --output build/m4/aclocal.m4

to the top-level Makefile.am.  I suppose:

 AC_CONFIG_MACRO_DIR(build/m4)

will then be sufficient for the tools to DTRT.  I haven't tried this
approach yet, having just learned about it, prompted by your query (so
thanks for asking!), however.  Does it work?
