[rc5] Sparc5 benchmark

While the new v2 client claims to be supersparc-optimized it even 
performs less fast on an SS 20 ('cpu0 is a "Model 71 SuperSPARC-II 
SPARCmodule" CPU') over here.

These are the results when I benchmark the clients:

	bash$ ./rc5-solaris-supersparc -m
	rc5-56-client: Performance testing with 1000000 crypts
	rc5-56-client: Complete in 12.390 seconds. (80709.57 keys/sec)
	bash$ ./rc5v2/rc5v2-supersparc -benchmark

	RC5 v2.000 client - a project of distributed.net
	Copyright distributed.net 1997
	Visit http://www.distributed.net/ for more information

	Benchmarking with 10000000 tests:
	.....10%.....20%.....30%.....40%......... [cut]
	Complete in 138.589 seconds. [72155.89 keys/sec]
	bash$

On a ss5 it does indeed perform a lot worse too. About 25%. I get about 
29K with v2 and 40K with v1.
