Subject: [PATCH] kernel: fix segmentation fault in mconf on linux

Commit 86c966a8ae9c4e74b912a16a760aaed17c68eb32 caused HOST_LOADLIBES to
include -lncurses. This was added for fixing build issues on macOS.
This introduces issues on Linux when wide-character ncurses is being
used for compiling, but the non-wide-character version is linked in.

Fix this by adding the extra override for HOST_LOADLIBES only on macOS.
