Parallelizes locale generation based on `BR2_JLEVEL` setting. Locale generation always runs during the finalize stage and can consume a significant amount of time. Parallelizing it greatly reduces that time on multi-core machines. To parallelize it, we first invoke `localedef` for every locale in parallel with the `--no-archive` option. This creates the intermediate locale data instead of writing to the finally archive directly. Then, we invoke `localedef` again once to create the archive from the intermediate compiled locale data files. We have to do it this way because `localedef` does not do any locking when writing to the archive file, so calling it without `--no-archive` concurrently could result in a corrupt archive file or an archive file that is missing some locales. While we're at it, make two additional improvements: - Remove locale-archive before adding to it. Otherwise, repeated applications of target-finalize will keep on growing the file. - Sort the locales when creating locale-archive so its contents are reproducible. We use `find` to collect the installed locales rather than LOCALES. This makes it possible for something else (skeleton, overlay, custom package) to create and install additional locales and still have them added to locale-archive.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
