I suggest to pass package version to command line:

  make MY_PKG_VERSION=$(git ls-remote http://repo.git/path master) all

You may also force versions using local.mk:

  override MY_PKG_VERSION = $(shell git ls-remote http://repo.git/path 
master)

However, these ways are not officially supported. Consider them
as hacks.

BR,
