[lldb-dev] Everyone: please download, build and test the new iohandler branch

Okay - so since Abid is seeing it as well, I'm inclined to put in both (1)
the makefile fix for non-cmake (i.e. configure-based) makes, and (2) the
explicit operator=.

We're tracing through an editline failure in a regex test at the moment.
 These are test failures, though, not build failures.  It is probably worth
it for me to get those two build break issues in, then, before we resolve
all the test failures.
