Update to 0.4.4.1:

o) SuperH (SH4) emulation is now somewhat more stable.

	  x)  GXemul 0.4.4:    A NetBSD/dreamcast Live CD works.
	  x)  GXemul 0.4.4.1:  A Linux/dreamcast Live CD also works.

o) PowerPC "G4" emulation is now stable enough to let NetBSD/macppc
   run from a disk image. (Installing actually worked before, but the
   NetBSD/macppc GENERIC kernel uses AltiVec instructions which were
   not implemented correctly.)

o) The PICA-61 (arc) and i80321 (evbarm) emulation modes now have their
   timers fixed at 100 Hz. A hardcoded speed like this is very ugly, but
   it is at least better than before (when the timer wasn't really
   running at any specific speed at all).
