------------------------+--------------------
 bastet used to install with the universal variant. Now it does not,
 because the makefile portgroup was changed to use compiler wrappers that
 contain `-arch` flags. The error is:

 {{{
 /opt/local/var/macports/build/_Users_rschmidt_macports_macports-ports-
 ryandesign-fork_games_bastet/bastet/work/compwrap/cxx/usr/bin/clang++ -MM
 Ui.cpp Block.cpp Well.cpp BlockPosition.cpp Config.cpp BlockChooser.cpp
 BastetBlockChooser.cpp main.cpp Test.cpp> depend
 clang: error: cannot use 'dependencies' output with multiple -arch options
 }}}

 Note that the invocation of clang++ does not have `-arch` flags, as they
 are not needed and would cause problems. But the clang++ wrapper script
 contains `-arch` flags, which cause the problem.
