qt4: add aarch64 support

Add aarch64 support for qt4 packages.

Most of the patches are derived from debian:
http://anonscm.debian.org/cgit/pkg-kde/qt/qt4-x11.git/tree/debian/patches

Add arch check to set right QT_ARCH.

Disable webkit temporarily for qt4 and qt4-embedded that they fail 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:

+Subject: [PATCH] Fix AArch64/arm64 detection.
+
+The detection needs to go before arm, else the system will detect AArch64/arm64
+as arm.
+
+This patch comes from Wookey, he has agreed to put it under BSD or Expat
+to allow it's inclusion in here:

+Subject: [PATCH] Add qatomic support for AArch64 (aka arm64).
+
+Patch by Mark Salter <msalter@redhat.com>
+licensed under BSD:
+
+<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=735488#195>
+
+This patch is known to not be the most correct way
+to implement them, as it seems to be possible to do it in a faster way,
+but should work non the less until we can provide something better.
