Based on comments here it sounds like GCC merged some level of support without 
submitting corresponding changes to the psABI. I don't have those patches to 
hand, but you can probably find them on the GCC patches list. I think we've had 
enough unexpected compatibility issues by now that it's not really justifiable 
to merge something that's meant to be a standard ABI without having the 
corresponding psABI patch (even if it appears simple). I don't think anyone has 
posted such a psABI patch but there is/was a tracking issue for it on the psABI 
repo.

@kito-cheng is the bigendian RISC-V work in GCC still active at all? I'm 
wondering if there's a connection you could help make for Djordje.
