[PATCH] libxenstat: avoid build race

[Jan Beulich <jbeulich@xxxxxxxx>]

Olaf reported observing

xenstat_qmp.c:26:10: fatal error: _paths.h: No such file or directory
.../tools/libs/stat/../../../tools/Rules.mk:153: xenstat_qmp.opic] Error 1

Obviously _paths.h, when included by any of the sources, needs to be
created in advance of compiling any of them, not just the non-PIC ones.

A similar issue (at the time of the report) in the building of
libxenstore was addressed by Jürgen's 9af5e2b31b4e ("tools/libs/store:
don't use symbolic links for external files").
