Yes. The issue is that recently libtool spits out
an obtuse error if it sees ${ACLOCAL_FLAGS} in ACLOCAL_AMFLAGS

libtoolize:   error: AC_CONFIG_MACRO_DIRS([m4]) conflicts with ACLOCAL_AMFLAGS=-I /opt/xorg/share/aclocal.
autoreconf: libtoolize failed with exit status: 1

i.e. it misses that we both include the user aclocal directory as well
as our own -I m4.

So I tried using it as a make variable instead, but then it is evaluated
as the shell $() command!
