View File 03_hide_std_symbols.diff of Package libQtWebKit4 (Project KDE:Qt)

From: Modestas Vainius <modax@debian.org>
SUbject: Make hide_symbols to cover all QtWebKit portions
Origin: vendor
Author: Timo Jyrinki <timo@debian.org>
Last-Update: 2013-01-28 (use a similar patch on Qt 5)
Forwarded: no

Almost everything in Source/WebCore/generated was not build with
-fvisibility=hidden resulting into redundantly polluted and huge dynamic symbol
list in libQtWebKit.so.

Therefore, move +hide_symbols configuration parameter upwards in order for it
to cover everything including the offending Source/WebCore/CodeGenerators.pri
