Description: ZeroVM fix under IA32. Actual code in
openjdk/hotspot/src/os/linux/vm/os_linux.cpp#safe_cond_timedwait
call get_fpu_control_word and set_fpu_control_word under
any IA32 arch.
In os_linux_zero.cpp, this methods throw errors with ShouldNotCallThis.
Just replace it with just NO-OP.
TODO: Maybe just add ifndef ZERO in os_linux.cpp
