The idea of the base class dependency is to say "yes, I need a C cross compiler"
and this was never meant to be gcc specific. Looking at the codebase, whilst we
code triplets into this, it does overcomplicate things as there are only ever
limited, "target", "sdk" and the class extended versions like mutlilib.
After much thought, we can simplify this to virtual/cross-cc and virtual/nativesdk-cross-cc.
This lets us remove the "gcc" specific element as well as removing the over
complicated triplet usage.
At the same time, change the much less widely used "g++" variant to "c++" for
similar reasons and remove the triplet from virtual/XXX-binutils too.
Backwards compatibility mappings could be left but are just going to confuse
things in future so we'll just require users to update.
This simplification, whilst disruptive for any toolchain focused layers, will
make improved toolchain selection in the future much easier.
Since we no longer have overlapping variables, some code for that can just
be removed. The class extension code does need to start remapping some variables
but not the crosssdk target recipe names.
This patch is in two pieces, this one handles the renaming with the functional
changes separate in a second for easier review even if this breaks bisection.

It was previously discovered that mcmodel=medany should be used for RISCV64,
however this was only being set for the applications themselves, but not for
newlib, this meant that we ended up with C library that used a code model and
an application that used another one which is not something we want.
Pass mcmodel=medany when building newlib for RISCV64 as well.
Also, s/CFLAGS/TARGET_CFLAGS to standarize across recipes, the variable
expansion provides no functional difference at this point.

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.

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.

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.
