Hi.
The ARC toolchain is doing something funky here, from openssh's config.log:

configure:10462: checking for strnvis

Which results in detecting strnvis which doesn't exist in linux at all.
If we go ac_cv_func_stnvis=no it's a hack and doesn't work completely
since it fails on other openbsd-compat detections making it fail to
build for other reasons.
Regards.
