Please try to build the daily packages for xulrunner-1.9.2 [1] for now
and update config.sub/config.guess to latest. in moz tree they are in
mozilla/build/autoconf/ ... diffing .guess manually with
/usr/share/automake/config.* showed me:

+			eval $set_cc_for_build
+			if echo __ARM_EABI__ | $CC_FOR_BUILD -E -
2>/dev/null \
+	        | grep -q __ARM_EABI__
+		then
+		    echo ${UNAME_MACHINE}-unknown-linux-gnu
+		    else
+		        echo ${UNAME_MACHINE}-unknown-linux-gnueabi
+			fi
+			exit ;;
+    avr32*:Linux:*:*)
     echo ${UNAME_MACHINE}-unknown-linux-gnu


which looks promissing to get over the configure stage at least.

probably unrelated and a follow up for now.
