From 25a5b9665d7d3c7603283847ff6a278f61812514 Mon Sep 17 00:00:00 2001 From: Matt Weber Date: Sun, 27 Oct 2019 15:59:02 -0500 Subject: [PATCH] toolchain: expose BR2_TOOLCHAIN_EXTRA_EXTERNAL_LIBS for all toolchain types 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/...).
