Your subject seems to imply that you have a problem building toolchains,
but in both cases it's a problem building a package for the host?

Strange. Ncurses builds here (also on Debian). What configure check
fails? (have a look at config.log in build/ncurses-5.6)

You have presumably enabled ccache support then.

This is autoconfig for the target - A pretty uncommon thing to build.

It seems like autoconf needs a dependency on m4. Could you try adding m4
to package/autoconf/autoconf.mk: AUTOCONF_DEPENDENCIES  and try again?

If that fails, check config.log to see what/why it fails.
