<pre>Ok, the problem here is the detection of THUMB2 support. Our code is based on __thumb2__ or __thumb__ defines. This does work on Debian:
$ gcc -dM -E - < /dev/null | grep -i thumb
#define __thumb2__ 1
#define __THUMB_INTERWORK__ 1
#define __thumb__ 1
#define __ARM_ARCH_ISA_THUMB 2
#define __THUMBEL__ 1
but does not on Fedora 24 with GCC 6.1. :
$ gcc -dM -E - < /dev/null | grep -i thumb
#define __THUMB_INTERWORK__ 1
#define __ARM_ARCH_ISA_THUMB 2
as the previously mentions defines are not presented there.</pre>
