Update to 1.76:

1.76    2014-10-26

- When searching for the local timezone we now look at /etc/timezone before
  /etc/localtime. The former is a much quicker check if it exists. Patch by
  Karen Etheridge. PR #3.

- The tools/parse_olson script now supports parsing the etcetera and systemv
  files. This is *not* enabled by default as it would generate zones that
  conflict with existing links for Etc/UTC and others. Patch by Alfie John. PR
  #1.
