1) Seperate lines in a Makefile are run in seperate shells, thus
   'cd' on a line on it's own is a NOOP.

2) When using GNU tar the produced tarfile had full paths starting from
   /

3) When creating include directories: child directories were created
   but not the parent, which doesn't work without 'mkdir -p'
