Don't conditionally define CACHE_LINE_SHIFT, as we anticipate sizing

Browse source 
a fair number of static data structures, making this an unlikely
option to try to change without also changing source code. [1]

Change default cache line size on ia64, sparc64, and sun4v to 128
bytes, as this was what rtld-elf was already using on those
platforms. [2]
