+Subject: [PATCH] configure.ac: Fix ncurses include when not cross compiling
+
+When not cross compiling, the ncurses include path used by configure.ac
+is hardcoded to a path on the user's development machine. Change this
+path to use ${prefix} so that it can use a host folder path specified
+by Buildroot.

The Diffoscope tool has a runtime dependency on the curses module in Python. Buildroot disables curses support for host-python3. This patch allows for ncurses to be a configurable option for the host-python3 package like it is for the target python3 package. An additional patch is added to fix the ncurses include path as it previously was not correct when not cross compiling.
