Bug#1103089: jnr-ffi: FTBFS

[Santiago Vila]

Hello.

In addition to what Lucas reported, this package fails to build for
me on amd64:

82% of the time on machines with 1 CPU
  6% of the time on machines with 2 CPUs

so maybe the issue is not about amd64/i386 but about overall speed.

I suggest that you try on your normal amd64 system using
GRUB_CMDLINE_LINUX="nr_cpus=1".

If that does not work please contact me privately, as I can
offer a VM where this high failure rate happens consistently.

Thanks.
