We have a simple application containing a QWebView which segfaulted during
loading a page on a CortexA9 (armv7 thumb2). After enabling debug information
for qtwebkit and remote debug session the point of segfault was detected in
Source/JavaScriptCore/llint/LowLevelInterpreter.asm:1082
callSlowPath(_llint_slow_path_new_func_exp)
Further digging around lead to similar source in:
* qtwebkit: Source/JavaScriptCore/assembler/ARMv7Assembler.h
* qtscript: src/3rdparty/javascriptcore/JavaScriptCore/assembler/ARMv7Assembler.h
In these files a class ARMThumbImmediate is declared and used in many places.
This lead me to the suspicion that compiligng for armv7 expects thumb support.
The following tests were performed:
* our application is working fine again
* qtscript and qtwebkit were build with
'ARM_INSTRUCTION_SET = "thumb"' => TUNE_FEATURES = "arm armv5 thumb dsp"
for qemuarm without issues
This is a partial/rebased revert of:

qtscript,qtwebking: disable thumb
* qemuarm builds fail when thumb is enabled
