12783	Make some existing solaris-specific flags only be used with the solaris studio toolset	anonymous		"When building in solaris it automatically incorporates the following
pre-processor definitions in a number of projects:

-D_XOPEN_SOURCE=500
-D__EXTENSIONS__

In either 1.45 or 1.46 these were only present in boost.asio but they've
since been propagated to a number of other projects.

These should only be defined when using the solaris studio toolset.
When building with the gcc toolset these definitions trip things
up when feature_tests.h is included."	Bugs	new	Boost 1.65.0	Building Boost	Boost 1.63.0	Regression
