No problem at all. I'm mostly going to postpone this now in favour of 
autobuilding bootable images (which needs some non-riscv specific 
preparation). 

Last thing I still did overnight was run the glibc testsuite in quemu-riscv32 
user emulation. The summary is below (and as suspected a bit of a massacre); 
I'll look at the details later sometime. 
If anyone else wants to poke at it, I've tarred up the full glibc build dir 
and uploaded it together with the build log, see
