Because for a long time, the drivers were broken? (I don't know.)

Because that allows it to set run paths to the compiler libs?
(I don't know either.)

It precedes my time anyway.  We should clean it up and disable it for
the compilers and systems where we know that it works.  That is a
separate issue, and hopefully we can keep it separate, but IIUC it
influences this patch series and how much work it is to get right.
Not sure which strategy would be easiest for you.
