libgcc-ia64.ver: Export _Unwind_GetBSP@@GCC_3.3.2.

	* config/ia64/libgcc-ia64.ver: Export _Unwind_GetBSP@@GCC_3.3.2.
	* config/ia64/unwind-ia64.c (_Unwind_GetBSP): New function.
	* unwind.h (_Unwind_GetBSP): New prototype.
	* libgcc-std.ver: Add empty GCC_3.3.2 version.
	* mkmap-symver.awk: For symbol versions with no exported symbols,
	don't put anything into version script, just change all symbol
	versions which inherit from it to inherit from its ancestor.
