[Solaris] Fix profiling


Hi,

after http://gcc.gnu.org/ml/gcc-patches/2011-04/msg02139.html profiling uses 
TLS support where available.  This breaks on SPARC/Solaris 8 and 9 (at least) 
because the associated libraries aren't linked in.

Tested on SPARC/Solaris 8 and SPARC64/Solaris 9 (the Solaris 10 machine isn't 
in very good shape right now), OK for the mainline?

	* config/sol2.h (LIB_SPEC): Link TLS support for profiling.
