From 61991db099f66348dddbc3408e7ee8c05bda85cb Mon Sep 17 00:00:00 2001

Subject: [PATCH] configure.ac: Add an option to disable host udev version
checks
In cross-compilation environment, the build host might have an outdated
udev or no udev at all. But the user may still want to build with the
enabled udev rule (for its udev-enabled target).
This patch adds a "--disable-udevchecks" option the disable build host
udev version check at configure-time and unconditionally install the
enabled udev rule. Without this new option, the behavior stays the same
(checks enabled).
