Subject: [PATCH] Fix a build error on linux platforms

Due to dl* function usage in Core/HW/atrac3plus.cpp on non-windows
platforms, Core library needs to be linked with -ldl flag on these
platforms.

Added a CoreExtraLibs variable in CMakeLists.txt to handle all
platform-dependent dependencies of Core, and added dl to this variable
on non-win32 platforms.
