More sparc g10 problems

[Tom Spindler]

The sparc is really quite picky with long longs and unaligned memory;
most specifically, it _requires_ that long longs be aligned along
8-byte boundaries. The tiger.c functions make rather extensive use of
long longs, but doesn't do checking to see if the memory is aligned,
and solaris2.5.1's malloc only guarantees 4-byte boundaries.

Normally, the posix function memalign() would be used, but all the
custom memory allocation routines make it a bit confusing to me as
to where it shoudl be put in.

In addition, since DIGEST_ALSO_TIGER is only defined when WITH_TIGER_HASH
is defined, much of the code breaks when DIGEST_ALSO_TIGER is not defined.
Here are the patches to let the code compile without WITH_TIGER_HASH
defined.

(incidentally, removing the (void) from the timezone checking routines
worked.)
