[Buildroot] [git commit branch/2017.02.x] package/ntp: fix build for toolchains without ssp

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ccf0e0767d6c73dd23852fad5de2900c6f88fd56
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x

ntp defaults to use ssp support
http://bk1.ntp.org/ntp-stable/sntp/harden/README

by using these flags
http://bk1.ntp.org/ntp-stable/sntp/harden/linux

If the toolchain lacks SSP support this patch forces ntp to use an
empty set of flags: http://bk1.ntp.org/ntp-stable/sntp/harden/default

Fixes
