File gas-2.17.90.pot should include the following msgid (I suppose):
#: config/tc-bfin.c:1181 config/tc-bfin.c:1197
msgid "%s:%d:Unknown operator found for arithmetic relocation"
At present source code with "Unkonwn" looks like:
fprintf (stderr, "%s:%d:Unkonwn operator found for arithmetic" " relocation",
I have checked in a patch to fix the two "Unkown" spelling mistakes in the
tc-bfin.c file. The rest of this PR is a duplicate of 5121.
