[dpdk-dev] [PATCH v2 1/2] ci: add travis ci support for aarch64

[Ruifeng Wang <ruifeng.wang@arm.com>]

Add Travis compilation jobs for aarch64. gcc/clang compilations for
static/shared libraries are added.

Some limitations for current aarch64 Travis support:
1. Container is used. Huge page is not available due to security reason.
2. Missing kernel header package in Xenial distribution.

Solutions to address the limitations:
1. Not to add unit test for now. And run tests with no-huge in future.
2. Use Bionic distribution for all aarch64 jobs.
