OpenBSD enables Indirect Branch Tracking (IBT) on amd64 and Branch Target Identification (BTI) on arm64, where hardware permits. Since Go generated binaries do not currently support IBT or BTI, temporarily mark them with PT_OPENBSD_NOBTCFI which prevents branch target CFI from being enforced on execution. This should be removed as soon asn IBT and BTI support are available.
