RUNTESTFLAGS is used to pass options to runtest; the list of those
options can be seen with runtest --help.  I've used --tool-opts to
specify flags that are passed to the compiler (the "tool") for every
invocation, but haven't figured out how to set environment variables
that will be recognized by the .exp files.  I suppose it would help
to read the documentation for expect.
