#7406 [C1] Fix fatal error: Thread holding lock at safepoint that vm can block on: tty_lock issue
Summary: Currently the MIPS FPU emulator uses eXecute Out of Line (XOL) on the stack to
handle instructions in the delay slots of FPU branches. Because of this MIPS
cannot have a non-executable stack. So just linking with -Wl,-z,noexecstack flag
