Subject: mono-config: let os=linux include other glibc platforms
Date: Mon, 28 Mar 2016 00:56:15 +0100

For the purposes of mono-config(5), let GNU libc-based platforms such
as GNU/kFreeBSD or Hurd be matched by os="linux" (rather than
"unknownOS").

dllmap entries for os="linux" are appropriate for those platforms.
