I don't agree with this PR, but I agree it is debatable.

The code *means* to skip envvars in AC_PATH_PROG when they are not
absolute.

I'm not sure I understand the relationship with the present problem.
IMHO, AC_PROG_PERL as I posted is what we want: people will not always
want the full path, and it is not in the `tradition' of AC_PROG_CC,
AC_PROG_AWK etc. to set the var to a path.  What we want is
AC_PATH_PROGing $PERL once computed.  Indeed, it probably means doing
some magic around AC_PATH_PROG.

Note: I'm ready to debate about AC_PATH_PROG skipping non absolute
envvars, but I'd like to first understand what the author meant when
s/he did this.
