[PATCH 4/7] [HACK] lto: shut up some warnings

[Arnd Bergmann]

Building with LTO currently causes some annoying warnings:

WARNING: modpost: missing MODULE_LICENSE() in drivers/vhost/vhost_scsi.o
see include/linux/module.h for more information
kallsyms failure: relative symbol value 0xffffffff81000000 out of range in 
relative mode

The modpost warning is a false-positive, the other one is so far
unknown. Both need a proper fix.
