[OE-core] [PATCH 6/9] qt4: add aarch64 support

[Kai Kang]

Add qt4 aarch64 support. Use same patches with qt-native. Add arch check
to set right QT_ARCH.

Disable webkit temporarily that it fails to build:

| runtime/JSValueInlineMethods.h: In constructor
'JSC::JSValue::JSValue(const JSC::JSCell*)':
| runtime/JSValueInlineMethods.h:242:78: error: cast from 'JSC::JSCell*'
to 'int32_t {aka int}' loses precision [-fpermissive]

It has been fix by Qt5, but didn't backport to Qt4. There is an still open
defect for it:
