Compiling code for ARM on my ~amd64 setup. NCurses fail with cxx USE enabled, otherwise work fine. Crossdev setup is basic (only USE and PYTHON vars modified) Reproducible: Always Steps to Reproduce: 1.

Crosscompiler was installed without "cxx" flag, that's why. Not sure if it's feature or bug. Second place, where I hit this bug, was gettext Even with disabled "cxx" flag it ends this way: "arm-linux-gnueabi-gcc: error: autosprintf.cc: C++ compiler not installed on this system". So maybe it should depend on c++ support?
What are you trying to do here? It looks like you aren't using <toolchain>-emerge when you should be. 1) Please post your `<toolchain>-emerge --info' output in a comment. 2) Please attach the entire sys-libs/ncurses build log to this bug report.

Seems like ${CXX} is expanded to an empty string in place of getting the right (cross-)compiler name I have the same problem cross-emerging gcc
There is a problem in the configure stage: checking if /usr/x86_64-gentoo-linux-gnu/armv6j-hardfloat-linux-gnueabi/gcc-bin/5.4.0/armv6j-hardfloat-linux-gnueabi-g++ works... checking if /usr/x86_64-gentoo-linux-gnu/armv6j-hardfloat-linux-gnueabi/gcc-bin/5.4.0/armv6j-hardfloat-linux-gnueabi-g++ works... no configure: WARNING: Ignore /usr/x86_64-gentoo-linux-gnu/armv6j-hardfloat-linux-gnueabi/gcc-bin/5.4.0/armv6j-hardfloat-linux-gnueabi-g++, since it cannot compile hello-world. configure: WARNING: You don't have any C++ compiler, too bad So a config.log would also be useful.
I had a CXX environment variable that pointed explicitly to g++, but when I remove it, ncurses compiles. So this is no more reproducible.
