Summary

gopass built for OpenBSD from the master branch will fail to link to syscall(2) at runtime once OpenBSD removes syscall(2) from libc.

There are two usages of syscall(2) that I could find: one is due to pledge (will be fixed by https://golang.org/cl/468095), and the other is in readline, which I've opened a PR for. Unfortunately, it doesn't seem that the owner is maintaining that readline library anymore, and a switch to that other fork might be needed, unless you wish to use a module replacement that points to my PR's branch.

Steps To Reproduce

$ pwd
/home/jrick/src/gopass
$ go build
$ ./gopass
gopass:./gopass: undefined symbol 'syscall'
ld.so: gopass: lazy binding failed!
Killed 

Expected behavior

gopass executes without hitting a lazy linking error.

Environment

• OS: OpenBSD
• OS version: -current with the full syscall(2) removal patch, including removal from libc
• gopass Version: master branch
• Installation method: repo

Additional context

A working gopass can be built with patches to x/sys and readline.
