[Buildroot] [PATCH 1/2] legal-info: fix detection of "override" packages

[Yann E. MORIN <yann.morin.1998@free.fr>]

Luca, All,

On 2016-03-05 00:39 +0100, Luca Ceresoli spake thusly:
> The ifneq ($$($(2)_SITE_METHOD),override) test will always match
> because SITE_METHOD is never set to "override". The result is that
> some packages are downloaded and extracted unnecessarily, although
> they are (correctly) not saved in output/legal-info/.
> 
> Fix by simply testing $(2)_OVERRIDE_SRCDIR instead: when empty, it
> indicates that the packages is neither a "local" site-method package
> nor a package that has its source directory overridden.
