Subject: [PATCH] ospoll: Fix Solaris ports implementation to build on Solaris
 11.4

Wrong version got committed, but wasn't noticed since it only builds
with meson, not autoconf.

Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>
(cherry picked from commit 0e8c0d2f238e5d50daaf4672bd80ad519673b5e3)
