Romain Naour 25589148f7 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.

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
