Suricata

It seems that attempting to compile as a PIE on HardenedBSD (and likely FreeBSD) causes linking errors. Attached is a build log. The HardenedBSD ports entry for suricata can be found here: https://github.com/HardenedBSD/hardenedbsd-ports/tree/master/security/suricata

I added a USES flag that forces the linker to attempt to link as a pie (LDFLAGS=-pie). I also added a USES flag that forces the linker to link with RELRO support.
