Since we now have an example recipe on meta-skeleton to
build baremetal applications using OpenEmbedded, a user
produced SDK should be able to run such application.
Include nativesdk-qemu on TOOLCHAIN_HOST_TASK so its
built inside the newlib based SDK.

Some baremetal applications might require support from libstdc++
On newlib based toolchains, libstdc++ can be built as a static
library that applications can then link against it.
Pass libsdtc++-(static)dev to LIBC_DEPENDENCIES allowing the
library to be present for cross compilation as well as on
sdk builds.

With GCCPIE being enabled by default with security_flags.inc the
compiler will by default attempt to compile and link programs as PIE.
The targets that use newlib and baremetal in general do not support PIE
or are otherwise unable to use it due to how embedded targets are
compiled and executed. As such it makes sense to disable PIE by default
for these libc's in order to prevent build failures.
For baremetal tclibc there are no libc features or implementation as
such there is no implementation for the strong stack protector by
default.

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.
