From 78acc472d9719316f22e002a009a998d9ceec29d Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Mon, 12 Apr 2010 22:28:05 -0500 Subject: Rename lib_generic/ to lib/ Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory.
