Subject: [PATCH] [CI] backward compatible executable compilation

Add a new static-executable target to use in Dockerfiles and restore
the $(EXECUTABLE) target to what it was before to for backward
compatibility.

The release process now builds static executables instead of
dynamically linked ones which makes them more portable. It changes the
requirements at compile time and is not backward compatible. In
particular it may break packaging that rely on the target that
currently creates a dynamically linked executable.
