[Buildroot] [PATCH 2/2] qt: Disable Webkit Module for old Linux threads

[Vicente Olivert Riera]

Qt Webkit Module uses pthread_getattr_np() which is not implemented in
the old Linux threads. This causes the following compilation failure:

wtf/StackBounds.cpp: In member function ‘void
WTF::StackBounds::initialize()’:
wtf/StackBounds.cpp:172:38: error: ‘pthread_getattr_np’ was not declared
in this scope
