Subject: The sparc (and possibly other?) NLM format requires a different way to
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=df561b1494eb7280f36b9ceae57a72d6b851f912;p=binutils-gdb.git

write exports, so add a write_export field to the backend data (and set it
to NULL for everything but the sparc).
