Description:
------------
when trying to cross-compile configure picked up the host iconv, not the target one, resulting in wrong paths later on and configure failing.

configure was called with configure --with-iconv=DIR (where DIR is the dir to find the iconv stuff).

This fails at two places. First one is due to a faulty test in acinclude.m4
It tests PHP_ICONV against "yes". However PHP_ICONV in my case contains the path so we should test against not "no"
(PHP_ICONV can be a dir because otherwise this code later on would not make any sense:     for i in $PHP_ICONV /usr/local /usr; do )

The following patch is for 5.2.13, but I have verified it is also in the 5.2 snap from today.

oops, made typo in patch
This line:
+  if test "$PHP_ICONV" != no"; then
is missing a " and must read
+  if test "$PHP_ICONV" != "no"; then

Uploaded a new patch.
Sorry for any inconvenience!

oh and the subject line is wrong this reports and fixes only one faulty test, the other one is reported and fixed in 53443

There is a check right after what you have quoted which handles the supplied path.
