[OE-core] [PATCH] ncurses: enforce creation of pkg-config files

[Enrico Scholz]

ncurses does not create its .pc files when the /usr/lib/pkg-config
directory does not exist in the sysroot.  Because ncurses will be built
very early, this directory might be missing and .pc files will not be
installed.
