riscv32, qemu-user: semi-functional, what goes wrong?

[Andreas K. Huettel]

Dear all, 

I'm trying to get qemu usermode emulation of riscv32 working.
I managed to cross-build a linux system, and have it mostly rebuild itself
(including gcc 3-phase bootstrap), however, something is broken in bash.

Which may very well be a qemu usermode emulation bug, as I'm told bash works
fine in a riscv32 system emulation.

Below is the output of the bash testsuite. Any advice on where to 
start looking for problems would be appreciated. 

Best, Andreas
