[PATCH] cell spu offloading printf and friends

[jschopp]

In the past I have sent out a series of patches that offloads various c99 stdio functions. 
    The newlib stdio functions are simply too large for the cell spu.  A simple hello 
world program will typically take in excess of 200K without this patch.  Given the cell 
spu only has 256K in total it makes it totally impractical to add a printf to a program.

This patch is meant to be small and straightforward in order to get a minimal amount of 
usefulness merged.

Later today I will send a second patch, which is larger and implements the rest of the 
functions.  If this first one isn't going to be accepted, please save me the trouble of 
getting the next one sent out, as it depends on this one.
