This applies 965f341aa9 ("build: fix host menu config targets using
ncurses") to the SDK top Makefile.
If there is a pkg-config in the staging dir, it will try to use it
instead of the host system's pkg-config; then it will fail to find the
ncurses package. Linux's default will be used, which fails in some
cases, such as recent Gentoo systems.
