Look at LINK_SPEC in iris6.h for some oddities, such as -exact_version.
It's possible that they don't actually work anymore, but presumably
somebody at some point had a use for them.  Maybe all of the linker
options are broken and nobody's noticed, which would be a pretty good
justification for flushing them!
