Fix prefix for FreeBSD, OpenBSD

[hodong-kim]

FreeBSD and OpenBSD typically use /usr/local as the prefix. This patch modifies the prefix.

Approved. Actually, I believe the best approach is to change Linux's prefix to /usr/local, too. But I'm not sure if there is anyone relying on the old behavior.

BTW, does NetBSD need it?

I haven't tried it on NetBSD, so I don't know.

This also needs to be fixed to take effect.

Tested manually on FreeBSD, and looks fine. I‘m merging it. Thanks!
