This is the v2 version of patches to support loongarch linker relax.
The new relocs document at here:
  https://github.com/loongson/LoongArch-Documentation/pull/77

The patch set changelog:

v1 -> v2:
1. Simplified a ld relax test.
2. Use the C99 designated initializer syntax for LARCH_opts.relax.
3. Fix one spelling error.

Not that ChangeLog entries are required anymore, but seeing this 
consistent formatting error hurts my nits.  Here and the rest of 
your patches:

ChangeLog continuation lines line up with a TAB character to the 
"*" on the first line, not the text on that line.  Like so:

<TAB>* loongarch-opc.c (struct ...
<TAB>the default value ...

See existing ChangeLog entries.

Also, now that I can take my eyes away from the error, I think 
it's "New member relax with the default value 1" but I guess 
that's more up to poetic freedom.

brgds, H-P
