From f2a2b9f445ab1e31fbb27a74744e9a2ededfce17 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Makefile.am: Avoid redirection of input and output files
Ensure that directory is created before its written to
This can cause a build race in a highly parallelised build where a directory is not yet created but
output file is being written using redirection e.g.
rst2man.py --strict --no-raw --no-generator --no-datestamp < ../git/monitor/iwmon.rst > monitor/iwmon.1
/bin/sh: monitor/iwmon.1: No such file or directory
make[1]: *** [Makefile:3544: monitor/iwmon.1] Error 1
Upstream-Status: Pending
