Hello Doug, All!

First, 1.5.3 is out, and it has a few fixes worth upgrading.
Second, in the 1.5 series, ncurses should still be installed in the sysroot,
see this code snippet from scripts/build/debug/300-gdb.sh :
---8<---
CT_DoLog EXTRA "Installing ncurses"
mkdir -p "${CT_SYSROOT_DIR}/usr/bin"
CT_DoExecLog ALL make DESTDIR="${CT_SYSROOT_DIR}" install
---8<---
Third, the ncurses build is just for internal use, as it is required to
build the native gdb (that runs on the target), beacause gdb has hard-
coded calls to some ncurses functions, and this is not de-configurable.
So the ncurses that crosstool-NG builds is not expected to be used by
anything else than crosstool-NG.
Fourth, the (upcoming) 1.6 series will no longer install the ncurses
library in the sysroot, and will link gdb statically against libncurses
(still keeping dynamic linking for the other libs, though).

Oh good! :-)

Well, to do it right, you should not rely on the ncurses in the sysroot in
the first place, and use your own version.
