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.

Use linker symbol and board configs to determine the start
and extent of remaining RAM present in a board and use
it as newlib's heap.

While we don't have a proper heap that can make use of all the
available RAM, make it possible for applications using Newlib to
configure the size of the heap exposed via the sbrk() hook.

This patch renames the 'exit' function from newlib/libc-hooks.c to
'_exit' since this is the correct name of the newlib system call.
This patch fixes some linking errors that occur when an applications
uses abort() or assert().

The way we build the libc files is not a real library that can be
used as a libc and makes managing the source files a bit
difficult, so lets revert back to building the c function files
like everything else in the system to avoid any confusion.

This options allows us to link against newlib instead of the
integrated minimal c library.
