Tried the trick with host-gcc but it doesn't work for me in vmware maemo 
appliance upgraded to bora 3.1. Tried both in arm and x86 targets. I 
wonder what is broken with host-gcc here

What works for me for 'make menuconfig' is commenting three lines in

scripts/kconfig/lxdialog/check-lxdialog.sh

to echo -lncurses always

#       $cc -print-file-name=libncurses.so | grep -q /
#       if [ $? -eq 0 ]; then
                 echo '-lncurses'
                 exit
#       fi

This allows make menuconfig to run inside arm target.
