[Buildroot] [PATCH v2 1/1] package/sysklogd: bump to version 2.1.2

[Joachim Wiberg <troglobit@gmail.com>]

Hi Andreas,

I noticed this hasn't been merged yet, so I thought I'd provide my
feedback.  Sorry for the delay!  Overall it looks good, and I have
a few questions, and a little reveal.

These two could also be relevant:

- RFC3164 style logging, fully RFC compliant not just BSD style
- RFC5424 style logging to file and remote log servers

Minor, spelling.

I actually released v2.2.0 the other day, and there's a SHA256 on GitHub
now.  This version comes with proper /dev/kmsg support on Linux, which
support multiple consumers, instead of the old /proc/kmsg support.  If
/dev/kmsg isn't found it falls back to the old.  It also has the build
fix for O_CLOEXEC and another fix for an ARMv5 build warning.

I've tested it with a few Bootlin toolchains in our NetBox repo, so it
should be a much smoother ride.

The logger tool that comes with sysklogd is quite advanced, allowing the
user to leverage the RFC5424 `syslogp()` API to its fullest.  However,
it collides with its namesake in BusyBox, but so does the logger tool in
util-linux.  I'd very much like to see it in Buildroot, but I can submit
a patch later to add menuconfig support :)
