Subject: [PATCH] package/linux-tools: add support for building tmon

Signed-off-by: Markus Mayer <mmayer@broadcom.com>
[Thomas:
 - tweak Config.in help text as provided by Markus
 - adjust commit log
 - add missing select BR2_PACKAGE_NCURSES
 - add missing dependency on host-pkgconf, used by the tmon Makefile
   to find ncurses
 - add logic to disable -fstack-protector when the toolchain doesn't
   have SSP support.]
