Trying to build this on Debian, I get 8 failures, but they all
seem to be white space differences. I've attached the
test-suite.log file.

That looks like you somehow are missing:
commit 704f5fc477efaf120980449e677deb563da8491f
Author: Mark Wielaard <mark@klomp.org>
Date: Wed Nov 29 15:43:26 2017 +0100
readelf: Adjust print_ops formatting.
Use only 2 spaces for index (there are never 10000, the most seen in the
wild is 64). Adjust re-indenting after GNU_entry_value.
Signed-off-by: Mark Wielaard <mark@klomp.org>
But that is a commit from elfutils-0.171.
Maybe you have a local patch that conflicts with it?
Cheers,
Mark

I somehow ended up with something that reverts it, no idea why.
After removing that everything seems to work.

The riscv backend is fairly new. I don't have access to a riscv setup,
so cannot easily check myself. I have CCed Andreas, who wrote the port
and might be able to diagnose what is going on.
The first failure is for the location description of a return value,
which is kind of expected since riscv doesn't have a
return_value_location backend function yet.
The other 3 failures are all for the self-tests doing unwinding and
look like either DWARF and/or .eh_frame information is missing.
