external-toolchain: hardcode the destination directory for a library
Until now, the function copy_toolchain_lib_root was copying a given library to the target filesystem by assuming that it should be at the same place it was in the toolchain sysroot. However, with Buildroot hiding libstdc++ in /usr/<target-name>/lib(64), this isn't correct, and it is probably safer not to rely on the toolchain organization anyway. Therefore : * Instead of having a single EXTERNAL_LIBS variable, we now have LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS, which respectively list the libraries that should be copied to /lib and /usr/lib. As of today, only libstdc++ is part of the second list. * The copy_toolchain_lib_root takes another argument, which is the destination directory of the library, relative to $(TARGET_DIR) Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
