core: allow br2-external trees to provide pre-configured toolchains
Since we have a choice for the pre-configured pre-built toolchains, there is no possbility for a br2-external to provide its own. The only solution so far for defconfigs in br2-external trees is to use BR2_TOOLCHAIN_EXTERNAL_CUSTOM and define all the bits by itself... This is not so convemient, so offer a way for br2-external trees to provide such pre-configured toolchains. To allow for this, we now scan each br2-external tree and look for a specific file, provides.toolchains.in. We generate a kconfig file that sources each such file, and that generated file is sourced from within the toolchain choice, thus making the toolchains from a br2-external tree possible and available in the same location as the ones known to Buildroot: Toolchain ---> Toolchain type (External toolchain) ---> Toolchain ---> (X) Arm ARM 2019.03 ( ) Linaro ARM 2018.05 ( ) Custom toolchain *** Toolchains from my-br2-ext-tree: *** ( ) My custom ARM toolchain *** Toolchains from another-br2-ext-tree: *** ( ) Another custom ARM toolchain ( ) A third custom ARM toolchain Signed-off-by: "Yann E.
