[gccsdk] Recently added atomic functions hang on pre-ARMv6 machines

Hi all

Starting with commit r7252, GCCSDK now has more complete support for atomic
functions. This is enough to allow SDL2 to build with GCC atomics instead
of it's own implementation. However, this does not work on pre-ARMv6
machines due to the use of LDREX and STREX instructions. Is it possible for
someone to take a look at this?
