Maxim Dounin 950b668076 Lower optimization level for Sun Studio before 12.1.
At least Sun Studio 12 has problems with bit-fields exposed by nginx code
(caught by test suite).  They seems to be fixed in Sun Studio 12.1.  As a
workaround use "-fast -xalias_level=any" for older versions, it resolves
the problem.
