Thanks for the link!  This seems somewhat similar to my problem, so I
removed all -lclangFoo arguments and used -undefined dynamic_lookup
instead, and the linker did not complain, but now when I try to run clang
with my newly built plugin, the compiler returns a 1 error code with no
error messages, and doesn't seem to be doing anything.
