Doc: update the compiler notes about Sun CC's STL not being supported

The default STL (Rogue Wave STL) is far too old for Qt. It doesn't
meet the ISO C++ 98 specification. Using a more recent (and
standards-compliant) STL like stlport4 enables Qt to build even
QtWebKit on Solaris.

Also change the note indicating we're using Sun Studio 12, not 8.

+    Please note that Qt 4.6 is stricter in its STL requirements and
+    that the default STL implementation used by Sun CC does not pass
+    those requirements. This does not affect binary compatibility and
+    you can continue to use STL in your own code, but Qt's
+    STL-compatibility functions will be disabled.
+
+    Sun CC ships with a secondary STL implementation (called stlport4)
+    which is standards-compliant and can be used by Qt. You can enable
+    it by passing the -library=stlport4 option to the compiler. Note
+    that this does not affect Qt's binary compatibility, but it may
+    affect that of other libraries and programs that use STL.
