Hi,
Attached patch adds preliminary support for Bitrig to binutils. The
patch only covers x86 support (Bitrig is a fork of OpenBSD specifically
targeted at amd64 & arm).
These are the minimal changes need to build binutils (tested on v2.25)
without the gold linker enabled.
happy to answer any question/test/amend changes.
