Config.in: security hardening: disable FORTIFY_SOURCE for gcc < 6
As reported in the bug report [1], gcc < 6 doesn't build when
FORTIFY_SOURCE is set to 1 or 2. The issue is related to the
upstream bug report [2] but the patch fixing the issue for gcc 6
has not been backported to earlier gcc versions.
Add a dependency on gcc at least version 6 to BR2_FORTIFY_SOURCE_1
and BR2_FORTIFY_SOURCE_2.
