Description:
------------
The PHP configure script will not find libpng. The same configure line works fine in 32-bit Redhat. I am running SUSE x64 Professional where all the libs are placed into /usr/lib64 folder. It looks like PHP is trying to get em from /usr/local/lib folder instead.




Reproduce code:
---------------
./php-4.4.0/configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --with-imap=/usr/local/imap-2004a --with-gd=/usr/lib64 --with-png-dir=/usr/lib64 --with-jpeg-dir=/usr/lib64/ --with-zlib-dir=/usr/lib64 --enable-gd-native-ttf --with-freetype-dir=/usr/include/freetype2



Expected result:
----------------
No configure error.

Actual result:
--------------
configure: error: libpng.(a|so) not found.

Libpng is in /usr/lib64 folder, see below:
