Re-merged patch by Robert Scheck <robert@fedoraproject.org> for zarafa >= 6.40.0, which corrects
the linking between the libraries. Without this patch, any PHP usage causes the PHP error message
"undefined symbol: _ZN10ECMemTable6CreateEP14_SPropTagArrayjPPS_". The second hunk is required to
avoid linking errors like "(.rodata+0x0): multiple definition of `IID_IUnknown'". This patch was
originally by Michel de Ron (Zarafa); http://forums.zarafa.com/viewtopic.php?f=1&t=2418&start=15
is providing some more details and information.
