THUMB2 support not correctly detected on Fedora with GCC 6.1.
https://bugs.webkit.org/show_bug.cgi?id=159083
Patch by Tomas Popela <[email protected]> on 2016-06-28
Reviewed by Carlos Garcia Campos.
On Fedora 24 with GCC 6.1. the __thumb2__ and __thumb__ are not
defined so the detection of THUMB2 support will fail. Look also
whether the __ARM_ARCH_ISA_THUMB is defined to fix the THUMB2
detection.
