[Qemu-devel] [PATCH 2/2] qemu-doc: include version number

[Paolo Bonzini <pbonzini@redhat.com>]

Note that TEXI2POD doesn't support @set/@clear, so pass the value
manually on the command line.

This patch partially undoes commit bd7f974796 ("qapi: Clean up build of
generated documentation", 2017-03-16).
