automatically set correct worker count on 32-bit archs The upstream e2guardian.conf has a message telling users they need to adjust the default number of http workers on 32-bit systems. Instead we should just do this automatically. . Ideally this would be done at runtime by the program itself, and the default value could simply be commented out. . This changeset introduces setting a functional http workers value based on the build architecture at build time. . This patch was originally contributed to e2guardian in Debian and Ubuntu by Steve Langasek steve.langasek@canonical.com. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1053343 . The patch has been rebased against v5.5 of e2guardian by Mike Gabriel mike.gabriel@das-netzwerkteam.de.
