From 8a0d1cbfcc0649b2696c9cf20f877366de259ce3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] CMakeLists.txt: Remove -mthumb-interwork
This option is meaningless with aapcs ABI
which is the default for Linux and android
for armv7+ architectures
As an aside it helps in compiling with clang
where this option is absent
