[CRIU] [PATCH] [v4] travis: enable compilation for ppc64le

[Andrey Vagin]

From: Andrew Vagin <avagin at virtuozzo.com>

qemu-static from ubuntu/xenial contains a required fix
and now we can execute compilation for ppc64le in travis.

v2: rebase on criu-dev
v3: set QEMU_CPU=POWER8 to avoid segfaults of qemu-ppc64le-static

> By default, both qemu and gcc5 produce code on ppc64el which will run on
> POWER7 platform.  However, in debian gcc build instruction, gcc is explicitly
> built to produce code for POWER8 platform, which, obviously has additional
> instructions.

v4: use ubuntu:trusty. xenial and wily has a bug:
Processing triggers for libc-bin (2.21-0ubuntu4.1) ...
/sbin/ldconfig.real: 5: /sbin/ldconfig.real: Syntax error: ")" unexpected
/sbin/ldconfig.real: 5: /sbin/ldconfig.real: Syntax error: ")" unexpected
