Jean-Baptiste Trédez 10fc02b984 linux: generate KBUILD_BUILD_TIMESTAMP date whith LC_ALL=C 
Fix kernel reproducible build if a non-C locale is used on the host
system.

When building the Linux kernel, scripts/gen_initramfs_list.sh does 'date
-d"$KBUILD_BUILD_TIMESTAMP" +%s'. In linux.mk, Buildroot sets
KBUILD_BUILD_TIMESTAMP to "$(shell date -d @$(SOURCE_DATE_EPOCH))".

For example, if LANG=fr_FR.UTF-8 is defined in the host system, it does
not work:

- LC_ALL=C date -d"$(LC_ALL=C date)" : ok
- LC_ALL=C date -d"$(LC_ALL=fr_FR.UTF-8 date)" : error

LANG/LC_ALL variables exported in the main Makefiles are not passed in
the $(shell ...) sub-shells.

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.
