I guess this happens only when the build system has sys-libs/ncurses[unicode], but the cross-compile target has sys-libs/ncurses[-unicode]. And also possibly limited on amd64 systems to those with LIBDIR_x86=lib.

There is probably some broken code that detects /usr/include/ncursesw and /usr/lib/libncursesw.so from the build system and tries to use it for the cross-compile.

cross building ncurses-5.9-r3 you get alot of:
"/usr/include/ncursesw" is unsafe for cross-compilation

This comes from:
  use unicode && do_configure widec --enable-widec --includedir="${EPREFIX}"/usr/include/ncursesw

in the ebuild.
I haven't figured out what to replace it with, any ideas?

For ncurses, see
  https://bugs.gentoo.org/show_bug.cgi?id=522586
maybe your python problem is similar

Mass closing of bugs reported against old versions of dev-lang/python.  If the problem still occurs with the current versions (i.e. newest in each visible slot), feel free to reopen.
