    gcc-cross.inc: Prevent native sysroot from leaking into configargs.h
    
    Prevent the native(sdk) sysroot path from leaking into configargs.h. The
    configargs.h header is intended to be static and unchanged as the
    content is used as a means of determining that a gcc plugin is built for
    the same gcc. This also effects the output of 'gcc --version'. Due to
    per recipe sysroots and staging, the sysroot path would be replaced with
    the sysroot local to the recipe thus changing the content of
    configargs.h.
    
    The sysroot path is replaced with a generic "/host" prefix which
    represents the host sysroot (e.g. native or nativesdk).
