[Committed] Move stuff around to allow for compiling other front-ends for SPU

[Andrew_Pinski at PlayStation dot Sony dot Com]

The problem here is that the SPU back-end uses a couple of C family 
front-end stuff without being in spu-c.c.
This fixes the problem by moving around a couple functions and setting of 
target variables so they only
get referenced by the C front-end or if they need to be referenced by 
generic code moved from spu-c.c to spu.c.

And yes there is missing documention in front of each function, I will fix 
that in my next set of patches.

Committed after a build and test for spu-elf.  Also built the f951 
front-end but 95% of the tests fail because of the
lack of POSIX functions in newlib like dup and access.

Thanks,
Andrew Pinski
