The toolchain-external-package infrastructure is just a copy of the toolchain-external commands, replacing TOOLCHAIN_EXTERNAL by $(2) and adding double-dollars everywhere. toolchain-external itself is converted to a virtual package, but it is faked a little to make sue the toolchains that haven't been converted to toolchain-external-package yet keep on working. The TOOLCHAIN_EXTERNAL_MOVE commands don't have to be redefined for every toolchain-external-package instance, so that is moved out into the common part of pkg-toolchain-external.mk. The musl-compat-headers dependency stays in the toolchain-external package itself. The musl ld link is duplicated in the legacy toolchain-external and the toolchain-external-package, because they have separate hooks. The handling of TOOLCHAIN_EXTERNAL_BIN deserves some special attention, because its value will be different for different toolchain-external-package instances. However, the value only depends on variables that are set by Kconfig (BR2_TOOLCHAIN_EXTERNAL_PREFIX and BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD) so it can easily be used in the generic part. So we don't have to do anything specific for this variable after all.

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
