Description:
------------
Configure goes OK, make gets nearly all the way through then 
fails near the end with this error:

/usr/bin/ld: unknown flag: -export-symbols
collect2: ld returned 1 exit status
make: *** [libs/libphp5.bundle] Error 1

I checked in the docs for OS X's ld and there doesn't seem 
to be an -export-symbols option defined. This option is in 
the original configure script, and ends up in the generated 
Makefile. Is there some alternative? Is ld broken on OS X?

I have tried this on a clean OS install with a fresh copy of 
PHP source. The only mildly odd thing in my setup is that 
I'm linking to some libraries from fink (apache2, JPEG, PNG 
etc). I have tried building with a simpler configuration but 
still get the same result.

Reproduce code:
---------------
Here's my configure:

CFLAGS='-I/sw/include' \
CXXFLAGS='-I/sw/include' \
CPPFLAGS='-I/sw/include' \
LDFLAGS='-L/sw/lib' \
'./configure' \

I don't know if the original problem of -export-symbols 
appearing is still a bug, but I checked through the docs 
from ./configure --help and removed a few apparently 
obsolete options and now it compiles and runs ok. My working 
config is now:

'./configure' \
'--disable-overload' \
'--enable-bcmath' \
'--enable-calendar' \
'--enable-dba' \
'--enable-exif' \
'--enable-ftp' \
'--enable-gd-imgstrttf' \
'--enable-gd-native-ttf' \
'--enable-mcal' \
'--enable-memory-limit' \
'--enable-pcntl' \
'--enable-shmop' \
'--enable-soap' \
'--enable-sockets' \
'--enable-sysvsem' \
'--enable-sysvshm' \
'--enable-track-vars' \
'--enable-wddx' \
'--sysconfdir=/etc' \
'--with-apxs2=/sw/sbin/apxs' \
'--with-bz2' \
'--with-config-file-path=/etc' \
'--with-config-file-scan-dir=/etc/php.d' \
'--with-curl' \
'--with-dom=/usr' \
'--with-freetype2-dir=/sw' \
'--with-gd' \
'--with-gdbm=/sw' \
'--with-gettext=/sw' \
'--with-iconv' \
'--with-imap-ssl=/sw' \
'--with-jpeg-dir=/sw' \
'--with-png-dir=/sw' \
'--with-ldap' \
'--with-mcrypt=/sw' \
'--with-mhash=/sw' \
'--with-mysql=/usr/local/mysql' \
'--with-openssl' \
'--with-pcre' \
'--with-pear' \
'--with-png' \
'--with-ttf' \
'--with-xml' \
'--with-xsl' \
'--with-zlib' \
'--without-oci8'

Apologies for any inconvenience, but I suspect this report 
may still be useful to anyone else running into similar 
problems.
