However, Config.in.legacy handling is missing. See Config.in.legacy which explains how to do it for string options. Thomas

This patch extends the "copy extra GCC libraries to target" feature to also work for internal toolchains. The variable has been renamed to be BR2_TOOLCHAIN_EXTRA_LIBS and the configuration option moved under the generic toolchain package. For external toolchains, the step that does the copy is still in the copy_toolchain_lib_root() helper which copies from the sysroot to the target. For the internal toolchain, the host gcc-final package does a post install hook to copy the libraries from the toolchain build folders to both the sysroot and target(!static). Examples where this can be useful is for adding debug libraries to the target like the GCC libsanitizer (libasan/liblsan/...).
