binutils-gdb/ld/emultempl/spuelf.em
Alan Modra a2c5833233 Update year range in copyright notice of binutils files 
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

goes. That's rather a lot of code, and we don't want to run
map_input_to_output_sections again because most sections are already
