    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)
    
    [YOCTO #11344]
