[Qemu-devel] [PATCH] tests/vm: Clean out old working directories on build

[Peter Maydell <peter.maydell@linaro.org>]

When we do a build inside one of the BSD VMs, first
delete any stale old build directories from the VM's
/var/tmp. This prevents the VM from running out of
disk space after it has been used for a dozen or
so builds.

The Ubuntu test VM has a similar issue, but it doesn't
put its test build directories in /var/tmp/ like the
BSDs, and I don't use it so I'm not sure what the right
rm command would be. Somebody else can fix it if they care...

Disclaimer: not actually tested yet, but obviously it will
get tested as part of applying it to master, which I'd
like to do so my pullrequest tests don't keep getting
tripped up by this bug.
