The explanation for this is probably analog to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45174#13 and the current set of configure cache variables you might have to override can be found at http://git.savannah.gnu.org/cgit/libtool.git/tree/tests/no-executables.at (there's one more missing for IRIX that I know of). So a workaround would be to manually add ac_cv_lib_dld_shl_load=no to $target/libstdc++-v3/config.cache, and then rerunning make. This still needs to be fixed in an automatic way. Cheers, Ralf
