Various changes to properly handle QEMU for Cortex M3.
This was solved by creating a new MACHINE qemu-cortex-m3.
Specifying MACHINE=qemu-cortex-m3 will select proper tuning
for the cross-compiler.
Typical usage:
$ MACHINE=qemu-cortex-m3 bitbake zephyr-philosophers

Removed the need for "poky.conf", as a consequence
some variables previously defined via poky.conf needed to
be re-defined: TARGET_VENDOR, TCLIBCAPPEND
Moved here default BOARD definitions.
Defined DISTRO_VERSION.

Cortex-M3 is not supported natively by oe-embedded, so we need to
do it here. With these changes it should be possible to run:
To build all Zephyr tests:
$ MACHINE=qemuarm bitbake zephyr-kernel-test-all
$ MACHINE=qemuarm bitbake zephyr-kernel-test-all -ctestimage
To build "philosophers" sample:
$ MACHINE=qemuarm bitbake zephyr-philosophers
Once built, you can run the created "philosophers" image in qemu
(at this point the various paths have to be entered manually):
$ ./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-arm \
-kernel ./tmp/deploy/images/qemuarm/philosophers.elf \
-cpu cortex-m3 -machine lm3s6965evb -nographic -vga none
