Comment (by Phyx-):

 Ah right. The one in the rts is never used by the runtime linker as it
 doesn't know its own dependencies. I.e. We never load librts inside ghci.
 So makes sense why that one isn't getting picked up.

 I remember adding because of a failing test, but I don't remember which
 one. But grepping through my local test archives that doesn't seem to ever
 fail for me. Could you compile that test with a debug rts and dump the
 linker log? I can try to figure it out then.
