This adds the necessary bits to utilize the x86_64 toolchain built by sdk-ng for x86_64 when toolchain variant is either zephyr or xtools. This allows decoupling the builds from the host toolchain. Newlib is also available with this toolchain so remove the Kconfig restriction on CONFIG_NEWLIB_LIBC. Signed-off-by: Daniel Leung <daniel.leung@intel.com>

If user mode is enabled, and MPU hardware has requirements that
|
|
regions be sized to a power of two and aligned to their size,
|
|
and user mode threads need to access this heap, then this is necessary
|
|
to properly define an MPU region for the heap.
|
|
|
|
If this is left at 0, then remaining system RAM will be used for this
|
|
area and it may not be possible to program it as an MPU region.
