[libvirt PATCH 1/5] syntax-check: Rework mock-noinline to get all files at once

[Martin Kletzander <mkletzan@xxxxxxxxxx>]

The script can break if the number of files does not fit one invocation and
xargs has to split it.  Instead pipe the list of files directly into the script
and in the script read them from stdin instead of the arguments.
