Shell assignment operator in BSD make != is ported to GNU make in
version 4.0, so 3.x doesn't work. I choose to drop BSD make support as
installing GNU make on *BSD systems is easier than installing newer GNU
make.
Closes#9387
The shell assignment operator != was introduced in GNU make 4.0, or
specifically the commit in [1]. This fix removes such usages and
fallback to a more portable syntax. Tested with:
* GNU make 3.82 on CentOS 7.2
* bmake 20150910 on CentOS 7.2, source RPM from Fedora 24 [2]
* GNU make 4.2.1 on Arch Linux (Arch official package)
* bmake 20160926 on Arch Linux (Arch official package)
* GNU make 3.82 on Arch Linux (Compiled from source)
* Apple bsdmake-24 on macOS Sierra, binary package from Homebrew
Thanks @bdeyal for the feedback of the first tests

'make lazy-extractors' creates the youtube_dl/extractor/lazy_extractors.py (imported by youtube_dl/extractor/__init__.py), which contains simplified classes that only have the 'suitable' class method and that load the appropiate class with the '__new__' method when a instance is created.
Add auto-updating of youtube-dl version in ISSUE_TEMPLATE
Move parts of template text and adopt makefile to new format
Moved the 'kind-of-issue' section and rephrased a bit
Rephrased and moved Example URL section upwards
Moved ISSUE_TEMPLATE inside .github folder.
Update makefile to match new folderstructure
It's the portable version of BSD make: http://crufty.net/help/sjg/bmake.html
The syntax for conditionals is different in GNU make and BSD make, so we use the shell
