[poky] [PATCH 2/2] mesa-demos: fix build issue with gcc dso linking change

[Nitin A Kamble]

From: Nitin A Kamble <nitin.a.kamble at intel.com>

All the libraries needs to be specified explicitely with the new gcc dso
linking change patch. This was causing build errors for this
recipe. Specifying the libpthread library explicitely for linking to work
without errors.
