bsd-compatible makefile

The "shell" function -- $(shell cmd), to execute cmd in the shell -- is a GNU extensions. There are two options: one of them is to use the grave accent, as in this proposed change; the other is to use the shell assignment operator "!=", originally found in BSDs and implemented by GNU make later.

... or it's also possible to use gmake instead of make in gdk install if in a BSD system

Restored source branch makefile-freebsd

I think I would prefer auto-detecting gmake in lib/gdk.rb. I don't think we should take on the burden of having to test the Makefile for BSD Make compatibility all the time.

We should also think about Makefiles in subdirectories that we use. The top-level Makefile should use a $MAKE variable to invoke the correct command.

• auto-detect gmake/make in lib/gdk.rb
• in lib/gdk.rb, instead of invoking make install etc., invoke #{make_command} install MAKE=#{make_command}

Nice to see you are using GDK on FreeBSD @gmesalazar :)

@jacobvosmaer-gitlab please let me know when I should go ahead and squash those commits up

@gmesalazar I am OK with the extra commits :) thanks for the MR and thanks for working with me towards this solution!
