commit: http://git.buildroot.net/buildroot/commit/?id=ad501b6634dc9d974da7e86299041fe441d58088
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The logging mechanism startup being in inittab, it isn't easy to
overcharge the default policy. With this patch, the startup of the
syslog daemon is moved to an init.d script, that can easily be
overwritten.

[Peter: use install -D]
