Thomas Petazzoni b2c24f584d package/pkg-generic.mk: increase precision of timestamps
Currently, the timestamps that we keep in build-time.log use a
second-level precision. However, as we are going to introduce a new
type of graph to draw the time line of a build, this precision is
going to be insufficient, as a number of steps are so short that they
are not even one second long, and generally the rounding to the second
gives a not so great looking graph.

Therefore, we add to the timestamps the nanoseconds using the %N date
specifier. A milli-second precision would have been sufficient, but %N
is all what date(1) provides at the sub-second level.

Since this is changing the format of the build-time.log file, this
commit adjusts the support/scripts/graph-build-time script
accordingly, to account for the floating point numbers that we have as
timestamps.

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.
