package/ply: add new package
PATCH v2 1/1 package/ply: add new package
ply is a light-weight dynamic tracer for Linux. By means of using the BPF it can attach probes to the linux kernel (e. g. kprobes).
It's a small alternative to LLVM based tracers for embedded systems.
Project page:
https://github.com/wkz/ply/releases
Documentation can be found here:
https://wkz.github.io/ply/
Tested with beaglebone_defconfig (uClibc-ng as well as glibc)
---
Changes in v2:
- project and download site (suggested by Tobias)
- configure.ac uses a fixed version string because of annoying messages ("fatal: not a git repository ...")

We don't use [PATCH 1/2] in patches, but just [PATCH]. This is detected and reported by "make check-package".

This was missing a significant number of dependencies:
- ply is only available for ARM, AArch64, PowerPC and x86-64
- ply uses fork(), so a dependency on BR2_USE_MMU was needed
- ply uses a number of BPF features, including some only available in Linux >= 4.6, so a dependency on >= 4.6 headers was needed

Some of those lines were too long, causing "make check-package" warnings.

We typically keep only the home page of the project, so I kept only this last URL.

Having the hashes of the patches is useless, as they are bundled with Buildroot. However, what is useful is to have the hash of the license file. Also, we separate fields in this file with two spaces.
I've applied after fixing the above issues. Many thanks for your contribution!
Best regards,
Thomas
