Suppress array bounds check for nacl build. · 1d1b8467

machenbach@chromium.org authored Jul 10, 2013

The NaCl and the ARM builder started failing to compile at revision 15593 with spurious array bounds warnings.

The ARM builder will be fixed by updating the cross-compiler version. Since the nacl compiler comes with the nacl toolchain, the warning will be suppressed for that builder.
