The toolchain wrapper will be reused for the internal toolchain, so it belongs in the toolchain directory. Also, the ext- prefix is removed from it. The build commands are moved to a new toolchain-wrapper.mk. The wrapper arguments that are also relevant for the internal toolchain wrapper are moved to toolchain-wrapper.mk, the rest stays in toolchain-external.mk. While we're at it, move the building of the toolchain wrapper to the build step of toolchain-external. There is no specific reason to do this, other than that it fits better semantically. Also remove the MESSAGE call, otherwise we'd see: >>> toolchain-external undefined Building >>> toolchain-external undefined Building toolchain wrapper /usr/bin/gcc ... Having an extra "Building toolchain wrapper' message is pointless. The useless condition on $(BR2_TARGET_OPTIMIZATION) is removed. It was always true because it wasn't qstrip'ped first, so clearly it works without that condition as well. Also rewrapped some comments and removed the 'external' reference.

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.
