Re: [9front] Cannot build system on latest rpi4 (libbio errors)

Not sure if it was meant to be required after Amavect's latest mk
changes, but I had to do this after updating to the latest commit.  I
had followed FQA 5 to just do mk install under /sys/src, which wasn't
sufficient. I'll comment again if I need to do it down the road but
thought I'd mention it.

> I attempted to resolve by first rebuilding /sys/src/cc, then /sys/src/7c, as mentioned in FQA 5. I then tried 'mk clean', and 'mk libs', and still no success.  I would have thought that a 'mk clean' would have worked, but from the message above it looks like the build is using the system's libbio and it's expecting different type signatures. I looked at the commit log for 9front but didn't see anything recently that would modify libbio.

Let me guess, that's upas? I think the mkfiles there need
another look -- I don't think we rebuild libcommon when
we should.

Try 'cd /sys/src/cmd/upas && mk nuke'.
