Thomas Petazzoni d6ce2a1681 arch/Config.in.x86: add option for -march=x86-64
We already have support for a wide range of x86-64 CPUs, but we don't
have any option to build for the most generic possible x86-64 CPU, as
made available by the -march=x86-64 GCC option.

This commit makes this option available in Buildroot.

It only really makes sense to use as a 64-bit CPU, and not as a 32-bit
one, so we guard it behind BR2_x86_64.

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 OFTC IRC.
