libssl and libcrypto detection algorithms fail after Ubuntu upgrade

My Qt based app is build on Ubuntu 11.04, with the standard config option of resolving libssl at runtime. After a system upgrade to Ubuntu 11.10, it fails to detect the ssl and crypto libs, thus, all QSslSockets fail.

Root cause:

qsslsocket_openssl_symbols.cpp uses a three stage approach to detect libssl:

1) search for SHLIB_VERSION_NUMBER - in my case, 0.9.8, which does no longer exists
2) search for plain *.so - only exists if the -devel package is installed, which is not the case on most end user's machines
3) search in standard paths - fails, since Ubuntu 11.10 ships libssl and libcrypto in /lib/i386-linux-gnu, which is neither in $LD_LIBRARY_PATH, nor in the search list
