linux-user: Handle TIOCSTART and TIOCSTOP

Browse source 
Some architectures (ppc, alpha, sparc, parisc, sh and xtensa) define the
BSD TIOCSTART and TIOCSTOP ioctls in their kernel headers to provide
compatibility to other operating systems.

Those ioctls are not implemented in Linux, nevertheless, bash will use
this ioctl if it's available on those architectures.

To avoid false warnings, add code to simply ignore those ioctls.
