Merge of r4004, r4005:

Solaris related fixes:

*) Detect POSIX semaphores in librt on Solaris (ticket #3).

Patch by Denis Ivanov.

*) 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.
