Description:
------------
I am trying to compile PHP on a clean install of debian wheezy (see commands to reproduce below).

./configure fails with the following messages:

checking for OpenSSL support... yes
checking for Kerberos support... no
checking whether to use system default cipher list instead of hardcoded value... no
checking for DSA_get_default_method in -lssl... yes
checking for X509_free in -lcrypto... yes
checking for RAND_egd... no
checking for pkg-config... no
configure: error: Cannot find OpenSSL's libraries


The problem is that the configure script does find the header files but not the libraries itself because they are not in the default location because of debian multiarch support. ld however is already configured to find the libraries in this path.

Here are the libs:

$ find / |grep libssl.so    
/usr/lib/x86_64-linux-gnu/libssl.so
/usr/lib/x86_64-linux-gnu/libssl.so.1.0.0

Here is the part of ld config:

$ cat /etc/ld.so.conf.d/x86_64-linux-gnu.conf 
# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu

I think the PHP configure script should not fail hard here if ld is able to find the libraries on its own. There is no need to take any action adding it to the ld command in this case.


Test script:
---------------
apt-get install -y git curl build-essential autoconf bison re2c libxml2-dev openssl libssl-dev
git clone https://github.com/php/php-src /opt/php/php-src
cd /opt/php/php-src
git checkout php-5.6.8
./buildconf --force
./configure --prefix=/opt/php/php-dist/php-5.6.8-custom --with-openssl
