Revert "os: Prevent backtrace from being stopped in noreturn functions."
This reverts commit 579715f830fbbca9e1ecb17dc18176132f5969e7.
The patch is not needed anymore. I haven't encountered backtrace
problems with GCC 4.3.3. Even if the problems still persisted, this
commit should be removed and instead the definition of _X_NORETURN
should be modified to be empty if GCC/ARM is used. However, currently
it seems that ARM backtraces are OK even if _X_NORETURN is used and
-mapcs-frame is not defined in CFLAGS.
