So I collected all three "issues" here and sent you the generated logs.

Hope this helps.

Feel free to add my credits.

Looks like the issue is related to trying to layer the Make-variable 
expansion.

In the shell (and most other languages) an assignment like:

$ ACLOCAL_AMFLAGS="${ACLOCAL_FLAGS} -I m4"

would take the current value of the existing ACLOCAL_FLAGS variable and 
use it construct the value of the new variable ACLOCAL_AMFLAGS. Thus if 
ACLOCAL_were "--XXX" this would yield "-XXX -I m4". Then later we'd see:

$ aclocal ${ACLOCAL_AMFLAGS} ...

which would use the value as previously defined.

Make doesn't do that. It sets ACLOCAL_AMFLAGS to "$(ACLOCAL_FLAGS) -I 
m4" and then later, when ACLOCAL_AMFLAGS is *used* it expands it, and 
then notices that the expanded version still contains a $(var) construct 
and expands *that* ... and so on until there are none left. This is 
sometimes useful, but often confusing. So GNU make (as POSIX, from 2012 
on) supports another type of assignment,

VAR ::= expression

which does the expansion of <expression> just once, at this point, and 
stores the result rather than the <expression> itself. So, try changing 
the line

ACLOCAL_AMFLAGS = $(ACLOCAL_FLAGS) -I m4

in the Makefile into:

ACLOCAL_AMFLAGS ::= $(ACLOCAL_FLAGS) -I m4

and see whether that helps :)

ACLOCAL_AMFLAGS = ${ACLOCAL_FLAGS} -I m4
=> autoreconf: running: aclocal ${ACLOCAL_FLAGS} -I m4
...

With setenv ACLOCAL_FLAGS "-I /opt/xorg/share/aclocal":

=> autoreconf: running: aclocal -I /opt/xorg/share/aclocal/ ${ACLOCAL_FLAGS} -I m4
autoreconf: configure.ac: tracing
autoreconf: running: libtoolize --copy
libtoolize:   error: AC_CONFIG_MACRO_DIRS([m4]) conflicts with
ACLOCAL_AMFLAGS=-I /opt/xorg/share/aclocal.

Using ACLOCAL_AMFLAGS ::= $(ACLOCAL_FLAGS) -I m4

=> autoreconf: running: aclocal -I /opt/xorg/share/aclocal/ 
autoreconf: configure.ac: tracing
autoreconf: running: libtoolize --copy
libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

It looks like using 
ACLOCAL_AMFLAGS = ${ACLOCAL_FLAGS} -I m4
is obsolete in autoreconf (GNU Autoconf) 2.69.
So looks like the answer is
	AC_PREREQ([2.69])
	ACLOCAL_AMFLAGS = -I m4

Not sure what the real fix of the reported "ACLOCAL_FLAGS issue" is.

As said in my initial asking I have here on Ubuntu/precise AMD64 autoconf v2.68.
Being no autotools-guru, version and feature check might make sense.
