If `select_from_ports` is evaluated lazily, we might miss a port during the dependency check. A way to prevent this is to use the `:=` operator. Fixes genodelabs/genode#4618

# Make sure that symlink modification times are handled correctly.
|
|
# Otherwise, the creation of symlinks that depend on their own directory
|
|
# behaves like a phony rule. This is because the directory mtime is
|
|
# determined by taking the mtimes of containing symlinks into account.
|
|
# Hence, all symlinks (except for the youngest) depend on a directory
|
|
# with a newer mtime. The make flag -L fixes the problem. Alternatively,
|
|
# we could use 'cp' instead of 'ln'.
