By passing --disabled-newlib-supplied-syscalls, newlib will disable the
generation of builtin syscalls and move this to libgloss. (This also
affects the generation of crt0.o.)
libgloss SHOULD then provide the syscalls, crt0.o and other functions that
are no longer part of newlib itself. This now means that you must link
with both newlib and libgloss, whereas before newlib would run in many
configurations by itself.

newlib to 3.2.0.
- Mentor Graphics added tcl license (amdgcn-* targets)

Newlibs Makefiles use a variable CC_FOR_TARGET to build
libraries for the TARGET machine (as opposed to
CC_FOR_BUILD).
We pass CC on our compile function, which is normally
use to build, although in this case, the configure
script is trimming CC and using simply gcc for the target
machine, basically taking out the TUNE variables we pass
in CC as well, such as march, mfloat-abi and such.
This causes errors when building applications since
CC will try to use hard floating point for example
whereas the libc.a from newlib will contain libraries
built with the defaults which could be soft floating
point for example.
e.g.:
$ ${CC} test.c
real-ld: error: test.out uses VFP register arguments,
/usr/lib/libg.a(lib_a-stdio.o) does not.
Analizing the object files we can see that one of them
uses soft (library) and the other one uses hard
floating point (program):
$ readelf -A test.out | grep VFP
Tag_ABI_VFP_args: VFP registers
$ readelf -A usr/lib/libc.a | grep VFP
Hence why the linker complains.
Pass CC_FOR_TARGET with the contents of CC to override
the trimming from the configure script and build newlib
with the correct tune.

We no longer have special "libc" for gcc so we can rely on plain
virtual/libc and reduce the complexity in the dependencies.

When installing libgloss libraries handle the ${TARGET_SYS}/lib contents
so that it is placed in ${libdir} instead of ${libdir}/lib. This
resolves a packaging QA issue.
ERROR: libgloss-3.0.0-r0 do_package: QA Issue: libgloss:
Files/directories were installed but not shipped in any package:
/usr/lib/lib
/usr/lib/lib/libnosys.a
/usr/lib/lib/nosys.specs
Please set FILES such that these items are packaged. Alternatively
if they are unneeded, avoid installing them or delete them within
do_install.
libgloss: 3 installed and not shipped files. [installed-vs-shipped]

This patch adds the posibility to build using TCLIBC=newlib.
It allows users to build baremetal applications with the use of a
C library.
Newlib is a lightweight C library meant to be used on embedded systems,
it is meant to be easily portable for new platforms and to provide
basic functionality on them, by design, it provides stubs for some of
these core functions declared as weak, so they can be built correctly
and then linked against some other library which provides specifics
about the platform being used if need be, libgloss takes care of these
in some cases, but it can also be extended, this patch also allows the
user to easily add other libraries to it by adding them to
NEWLIB_EXTENDED for this specific reason.

Newlib is a C library that is intended to be used on embedded systems.
It is a conglomeration of several library parts, all under free software
licenses that make them easily usable on embedded products.
Newlib provides a C library alternative that can run on baremetal, mainly
for resource constrained devices.
Libgloss is the BSP part of the C library, which can be easily modified
to port for new hardware platforms.
