[Buildroot] [PATCH 1/1] ncftp: fix cross-compilation issues

[Romain Naour]

ncftp is unable to find ncurses library installed by ncurses package.
So ncftpbookmarks is not build and install fails.

If ncurses is installed on the host machine then ncftp find it
and build ncftpbookmarks.

To avoid that, we need to remove the cross-compilation test in
configure script and set ac_cv_prog_cc_cross=yes in ncftp.mk

Sadly, autoreconf don't work with this package.
