Actually I care about Xen and 9pfs support, it is one of the few
combinations that I use regularly and it is even enabled in the Xilinx
product I look after. But admittedly I don't test QEMU master as much as
I should. With the recent changes to the build system it is not very
suprising that there are some issues. It would be great to have a Xen
and 9pfs test in the gitlab CI-loop.


FYI I tried to build the latest QEMU on Alpine Linux 3.12 ARM64 and I
get:

  ninja: unknown tool 'query'

Even after rebuilding ninja master by hand. Any ideas? I don't know much
about ninja.


So I gave up on that and I spinned up a Debian Buster x86 container for
this build. That one got past the "ninja: unknown tool 'query'" error.
The build completed without problems to the end.

Either way I can't reproduce the build error above.
