legal info: fix saving of host package licenses Due to some tricky make behavior, the license texts of host packages that did not provide an explicit HOST_FOO_LICENSE_FILES definition was not saved. The problem is that it is not straightforward to use a variable defined/updated inside an evaluated block as input to a foreach statement. If you try to use $(FOO) then only the original value of FOO is used for foreach, any update inside the block is ignored. However, if you use $$(FOO), the entire contents of FOO (typically a list of items) is passed as one item to foreach, thus causing just one iteration instead of several. >From Arnout Vandecapelle's explanation: Any variable referenced with a single $ inside the inner-generic-package macro is expanded before the resulting contents are eval'ed. Therefore, it is not possible to refer to variables defined by the inner-generic-package macro from within a single-$ function call. To fix the problem, one should defer the evaluation of the entire block using double dollar signs. Additionally, a few empty lines have been added to the legal-info-foo block for clarity.
