Take 2: CRIS/CRISv32 port, newlib part (first part)

Newlib patch applied. I believe the top-level configure.in has to applied to
gcc as well. I'm having trouble generating the new configure - I use autoconf
2.13 in newlib and for some reason the copy of 2.59 I have around is kacking.
Therefore, you go ahead and check the top-level change in and I'll figure it
out later.
