gcc-4.3.2: use multilib on sh4, so kernel can compile without fpu 
registers
* add patch gcc-4.2.3-linux-multilib-fix.patch used by various other
  linux distributions
* put the mulitlib config in gcc-cross4.inc because gcc-3 works without
  that
* need to bump PR because we pushed in earlier changes on sh4 without
  bumping
