The copy_toolchain_sysroot helper features a complex rsync loop that copies various directories from the extracted toolchain to the staging directory. The complexity mainly stems from the fact that we support multilib toolchain tarballs but only copy one of the multilib variants into staging. Increase understandability of this logic by explicitly restricting the rsync excludes to the iteration of the for loop they are relevant for. Additionally, update the function comment. Note: all attempts to reduce duplication between both rsync while keeping things nice and readable failed. One has to be extremely careful regarding line continuation, indentation, and single vs double quoting. In the end, a split up rsync seemed most clean.

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