[PATCH 0/3] Cell SPU offloaded stdio (take 2)

[Kazunori Asayama <asayama at sm dot sony dot co dot jp>]

This series of patches implements offloaded stdio functions on Cell
Broadband Engine SPU according to Joel-san's strategy in:

  http://sourceware.org/ml/newlib/2006/msg00843.html

This implementation consists of the following three parts:

  - Target specific stdio directory
  - FILE related stuffs for SPU
  - Other stdio functions for SPU

Most of the implementation comes from his patches in:

  http://sourceware.org/ml/newlib/2006/msg00820.html

I performed just several cleanups against the previuos patches:

  http://sourceware.org/ml/newlib/2007/msg00022.html

I tested the patches by using our testsuite (calling all offloaded
functions w/ various arguments and comparing returned values and
output w/ expected data).

OK to commit ?
