[PATCH] --with-apr=/path/to/apr-config does not work

If you try running Subversion's configure with
    ./configure --apr-path=/path/to/apr-config
then it won't take the apr-config because the current code in
ac-helpers/find_apr.m4 does this:

    if test -x "$withval/bin/apr-config"; then
      apr_found="yes"
      apr_config="$withval/bin/apr-config"
    elif test -f "$withval/libapr.la"; then
      apr_found="yes"
      apr_config="$withval/apr-config"
** elif test -x "$withval" -a "`$withval --help > /dev/null`"; then
      apr_found="yes"
      apr_config="$withval"
    fi

This test always fails. The patch checks for the successful running of
apr-config, not if there's output.

Best,
Blair
