--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- >../gnu/libgnu.a I bet it is due to how ../gnu/libgnu.a is generated. Does it use gcc-ar or just ar? For 4.9 and above, we use slim lto object files so it does not produce a symbol table that ar does not understand without a plugin and gcc-ar forces the plugin to be loaded.
