`native_client/src/trusted/service_runtime/linux/nacl_bootstrap.gyp` is willing to remove those flags, but the GBS default CFLAGS is appending at the tail, which cause those flags is added in when building nacl code. I do not think it is nacl code issue.

I have to disable those GBS flags globally to resolve the nacl code issue, any good idea for that?

And what the JIRA about? To ask GBS remove those flags by default?
