You're right. This doc belongs in the INSTALL file, because this is what
people installing GNU packages are supposed to read.

A proposed wording, to be added to the section "Particular Systems", is:

On Solaris, don't put @code{/usr/ucb} early in your PATH.  @code{/usr/ucb}
contains several dysfunctional programs; working variants of these programs
are available in @code{/usr/bin}.  So, if you need @code{/usr/ucb} in your
PATH, put it @emph{after} @code{/usr/bin}.

The section "Particular Systems" is introduced by the proposed patch in
  http://lists.gnu.org/archive/html/autoconf-patches/2008-04/msg00050.html
