[OE-core] [PATCH] ghostscript: check for incompatible TARGET_ARCH

[rebecca.swee.fun.chang at intel.com]

From: Chang Rebecca Swee Fun <rebecca.swee.fun.chang at intel.com>

The following warning occurs when building with meta-zephyr
with MACHINE set to arduino-101-sss:

WARNING: /srv/sdc/builds/11319/meta/recipes-extended/ghostscript/ghostscript_9.20.bb: Unable to get checksum for ghostscript SRC_URI entry objarch.h: file could not be found

This is due to the the TARGET_ARCH = "arc" for meta-zephyr is not
supported by ghostscript and causing bitbake unable to locate the
correct config file during recipe parse.

Adding a checker in recipe to raise a SkipRecipe exception if
it is not one of the supported architectures. This would then
only display an error if someone specifically tries to build
the recipe as shown below:

ERROR: ghostscript was skipped: ghostscript is incompatible with target arc
