Changes in sparc64-linux:
REGRESSION: Build libdnew1a.so with --Bsymbolic-functions --dynamic-list-cpp-new
REGRESSION: Build libdnew1b.so with --dynamic-list-data --dynamic-list-cpp-new
REGRESSION: Run with libdl3a.so
REGRESSION: Run with libdl3c.so
REGRESSION: Run with libnew1a.so
REGRESSION: Run with libnew1b.so
