ghostscript: check for incompatible host

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 checker in the recipe to raise an exception if the target
architecture is "arc". This would then only display an error if
someone specifically tries to build the recipe:

ERROR: ghostscript was skipped: incompatible with host arc-yocto-elf (not in COMPATIBLE_HOST)
