I also had a look and felt any change was a potential issue for some other reason I would not be aware of. We will use this patch in RTEMS until the next binutils release.

I am not sure if this approach is the correct way to fix the issue, but it does seem to be the simplest. As far as I can tell, the relocs in the .eh_frame section can eb unaligned, so using R_SPARC_UA32 seems to be the correct thing to do. I did look to see if I could enable sparc_no_align_cons when fixing the output for the .eh_frame section, but I could not find an easy way to do this. Hence I went for a hack based on the section name. Not very subtle, but if it works then that is enough for now.
