With latest host vanilla 4.0.0-rc3 kernel I get a similar picture:
TUN/TAP backend -
winch_thread : TIOCSCTTY failed on fd 1 err = 1
EXT4-fs (ubda): mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) readonly on device 98:0.

And I tried the vanilla gcc too instead of the hardened gcc, but no successs :
tfoerste@t44 ~/devel/linux $ sudo gcc-config -l

[2] x86_64-pc-linux-gnu-4.8.3-hardenednopie
