Many people have noticed a problem with this patch.  The problem was
that the newly-added --tag CXX was clobbering the effects of --tag
disable-shared.  This patch fixes it.  I've verified that
libsupc++convenience is no longer empty, and libstdc++ now contains
all of the libsupc++convenience object files.  I'm checking this in
mainline and 3.0 branch.  Sorry about the inconvenience :-(
