      c++: error: linker command failed with exit code 1 (use -v to see
invocation)

    This is because lld 17 defaults to errors when undefined symbols are
    referenced in linker version scripts. The problem is due to the Makefile
    JvmMapfile.gmk, which generates a linker version script. It uses "nm
    --defined-only" to dump symbols in object files, but this also includes
    local (hidden) symbols. Add "--extern-only" to make it only dump global
    symbols.
