A tool chain bug is something like this:
/opt/rtems-4.11/lib64/gcc/avr-rtems4.11/4.7.3/avr51/libgcc.a(emutls.o): In
function `__emutls_get_address':
/home/sh/archive/gcc-4.7.3/libgcc/emutls.c:139: undefined reference to
`__atomic_load_2'
/home/sh/archive/gcc-4.7.3/libgcc/emutls.c:150: undefined reference to
`__atomic_store_2'
collect2: error: ld returned 1 exit status
Its the job of the AVR maintainer/user to fix this.
