Is there any particular piece of documentation we should improve to make
it more obvious that $M4 must point to the binary, rather than the
directory containing the binary?

>>> autom4te: need GNU m4 1.4 or later:
>>> /global/homes/d/dmitryp/m4-1.4.16/install/bin

Hmm, this message is quoting the name of the "binary" it tried to
execute (and executing a directory doesn't do much), but it might be
more helpful if it added a blurb about EISDIR; I wonder if it's worth
trying a patch along those lines.
