Subject: [PATCH] build: use wxneeded on openbsd
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On OpenBSD 6.0 and greater W^X is enabled by default. All executables
that violate W^X need to be marked with PT_OPENBSD_WXNEEDED. In
addition to this, they must be executed from a filesystem mounted with
'wxallowed'.

More info on W^X: https://en.wikipedia.org/wiki/W%5EX
