The code to prevent using `PPCXCOFFMCAsmInfo` with little-endian targets used an incorrect check. Also, there does not appear to be sufficient earlier checking to prevent failing this check, so the check here is upgraded to be a `report_fatal_error`. `PPCAIXAsmPrinter` was also missing a check against use with little-endian targets. This patch adds such a check in.
