Subject: [PATCH 2/3] Have different definitions of __pthread_tsd_main agree
 in size

When switching optimization to higher levels (-O3) and enable link time
optimization (-flto) gcc finds two instances of the __pthread_tsd_main
variable that are declared with different sizes.

The real size that is needed is known in both source files. Just use
equivalent definitions.
