OS X: Add RPATH support for Mac.

RPATH support is activated on targets that have the MACOSX_RPATH
property turned on.
For install time, it is also useful to set INSTALL_RPATH to help
find dependent libraries with an @rpath in their install name.

Also adding detection of rpath conflicts when using frameworks.
