Author: arichardson

New Revision: 342101
URL: https://svnweb.freebsd.org/changeset/base/342101

Log:
  Allow bootstrapping libnv on macOS and Linux
  
  MacOS/Linux do not define struct cmsgcred but we need to bootstrap libnv
  when building on non-FreeBSD systems. Since they are not used during
  bootstrap we can just omit these two functions there.
