enable_mixed_bcp Tunable

The enable_mixed_bcp tunable is no longer supported in this release. In Solaris releases prior to the Solaris 9 operating environment, the /etc/system variable enable_mixed_bcp could be set to 0 to disable dynamic linking of partially statically linked SunOS^TM 4.0 and compatible executables. The system used dynamic linking for these executables by default. In the Solaris 9 operating environment, dynamic linking is always used for these executables, and the enable_mixed_bcp tunable has been removed from the system. This change does not affect binary compatibility for SunOS 4.0 and compatible executables in any way.
