Quincey Koziol b047710a95 [svn-r12669] Description:
Use a slightly less efficient method of computing the log2() on SGI IRIX64,
in order to avoid a compiler bug when optimizations are turned on.

Tested on:
    SGI IRIX64 6.5 (atlantia)

# IRIX's pmake confuses automake (as of version 1.9) if dependency tracking

# tracking on IRIX is simpler to implement than detecting pmake, detecting
# when a build is not in-place, and then disabling dependency tracking.
