Fix compile error on ARM and GCC < 4.1.0
Since b29ecbd (OTP-10418, R15B03) Erlang does not compile anymore with
old versions of GCC that do not have atomic ops builtins on platforms
where there is no native ethread implementation (e.g. ARM):

from hipe/hipe_mkliterals.c:29:
../include/internal/gcc/ethr_membar.h:49:4: error: #error "No __sync_val_compare_and_swap"
This patch adds a header guard in "gcc/ethread.h", as is present in
"libatomic_ops/ethread.h".
