[Pkg-uml-pkgs] failed i386 build of user-mode-linux 4.7-1um-2

[Ritesh Raj Sarraf]

Hello Mattia,

In my opinion, the best fix for this issue seems to be to build the kernel with
gcc-5. I propose the changes (patch attached). The same approach is what the
Debian Kernel team too has taken.

I have built the UML kernel successfully on both the architectures, with the
proposed patch.

Please let me know what you think. I have not pushed the change yet. Will do
after an ack from you.


Thanks,
Ritesh
