Gilles Chanteperdrix 9befe94baf Makefile: generate SOURCE_DATE_EPOCH for reproducible builds
When reproducibility is requested, generate a global SOURCE_DATE_EPOCH
environment variable which contains either the date of Buildroot last
commit if running from a git repository, or the latest release date.

This means that all packages embedding build dates will appear to
have the same build date, so in case of new commit or release, all
packages will appear to have been changed, even though some of them
may not have changed in fact.

The meaning of SOURCE_DATE_EPOCH is specified by the following
specification:
  https://reproducible-builds.org/specs/source-date-epoch/

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.
