Duncan,
   Yes, the result from "./TargetInfo -p" is incorrect under darwin10...

x86

In FSF config.guess, we had to add...

    *:Darwin:*:*)
        UNAME_PROCESSOR=`uname -p` || UNAME_PROCESSOR=unknown
        case $UNAME_PROCESSOR in
            i386)
                eval $set_cc_for_build
                if [ "$CC_FOR_BUILD" != 'no_compiler_found' ]; then
                  if (echo '#ifdef __LP64__'; echo IS_64BIT_ARCH; echo '#endif') | \
                      (CCOPTS= $CC_FOR_BUILD -E - 2>/dev/null) | \
                      grep IS_64BIT_ARCH >/dev/null
                  then
                      UNAME_PROCESSOR="x86_64"
                  fi
                fi ;;
            unknown) UNAME_PROCESSOR=powerpc ;;
        esac
        echo ${UNAME_PROCESSOR}-apple-darwin${UNAME_RELEASE}
        exit ;;

to make sure that the architecture was set to the default code generation
of the system compiler and not the default code architecture of the running
kernel.
