[v2,026/109] virtiofsd: Add Makefile wiring for virtiofsd contrib

Commit Message

Dr. David Alan Gilbert Jan. 21, 2020, 12:23 p.m. UTC

From: "Dr. David Alan Gilbert" <[e-mail]>

Wire up the building of the virtiofsd in tools.

virtiofsd relies on Linux-specific system calls and seccomp.  Anyone
wishing to port it to other host operating systems should do so
carefully and without reducing security.

Only allow building on Linux hosts.
