Ok - this appears to be an Irix specific extension to the ELF spec. An extension which is not currently supported by the binutils. Do you have a *small* self-contained example that can reproduce the problem ? Preferably one that can be run using a cross-compiler as I do not have access to an Irix host. Failing that, can you supply a binary that contains one of these OPTIONAL symbols so that I can investigate further ? In the meantime if you would like to try out the patch I am uploading to the PR, you may find, just possibly, that it helps.
