alignment fix

Description of problem:
In the implementation of tiger_final() in tiger.c, the array "temp" is defined as "mutils_word8". However, later it is used by typecasting it to ((mutils_word64*)temp). This unaligned access causes problems on ARM and as a result, TIGER's test fails.

Version-Release number of selected component (if applicable):
I have used mhash-0.9.9-7 version of mhash in the investigation.

How reproducible:
Try to build mhash on ARM on f11 root. 
A sample build can be found here: 
http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=42736


Actual results:
TIGER test failed.


Expected results:
All tests should succeed. 


Additional info:
I have attached a patch which forces 64-bit alignment on "temp". mhash built successfully on ARM with this patch. Kindly review and let me know whether it is correct.
