+Change handling of PKG_CONFIG_LIBDIR
+
+When PKG_CONFIG_LIBDIR was unset in the environment, the configure
+script was deducing the PKG_CONFIG_LIBDIR from the location of the
+pkg-config binary, which doesn't make a lot of sense, and isn't done
+by other autotools based packages.
+
+Also, the configure script was checking that the directory really
+exists. This forced to create the directory *and* provide an absolute
+path in PKG_CONFIG_LIBDIR, which didn't play well with the fact that
+at installation time, PKG_CONFIG_LIBDIR is suffixed to DESTDIR, which
+means that we got two times the staging directory location.
+
+This patch fixes both of those issues. Also, since ncurses uses a fork
+of autoconf 2.13, we can't simply use _AUTORECONF=YES, so we also fix
+the configure script in this patch.
