Hi Bernhard,

 the problem arises because there is no pkg-config installed and the
libraries are in /usr/local/{lib, include}.

 With pkg-config installed or libraries linked in /usr/{lib, include}
everything is fine without any specific flag.

 I have tried at first attempt but it did not work, I have also tried to
found a patch

make HOSTCFLAGS='-I/usr/local/include/ncursesw'
HOSTLDFLAGS='-L/usr/local/lib' -C src menuconfig

make: Entering directory '/mnt/sdb4/tinycore-editor/busybox/src'
  HOSTLD -L/usr/local/lib scripts/kconfig/lxdialog/lxdialog
/usr/local/bin/ld: scripts/kconfig/lxdialog/checklist.o: in function
`print_item':
checklist.c:(.text+0x40): undefined reference to `wmove

the result is the same with and without this patch that helped me to show
the command.
