Basic build framework for Nios2. Everything is stubbed out,
we just want to have a build going so that we can start to
parallelize implementation tasks.
This patch is not intended to be functional, but should be
able to produce a binary for all the nanokernel-based
sanity checks.

When capping the the absolute value of the width modifier in printf(),
it must first be cast to an 'unsigned'. This stems from the fact that
in two's complement, not all negative numbers have a positive counterpart.

Some parts of Newlib, notably the locale handling stuff, will try to
call open(), and if it's not provided, any application that for some
reason is bringing in that code will fail to link.
Having a non-working implementation keeps that code working.

Updates the minimal libc headers for differences between the C and C++
languages. This includes ...
1. Conditionally defining "bool", "true" and "false" as they are
already keywords in C++.
2. Making the definition of NULL language dependent.
3. Using the _Restrict macro instead of the restrict keyword as
restrict exists in C, but not in C++.
4. Changing the definition of size_t so that it is compatible with
what the compiler expects when building the new operator stubs
(as it varies by architecture).
