[gentoo-dev] [PATCH 1/3] eclass/kernel-{build,install}.eclass: link to config,Sys.map in moddir

[Andrew Ammerlaan <andrewammerlaan@gentoo.org>]

The kernels 'make rpm-pkg' and 'make deb-pkg' install the config
and System.map into the modules directory for easy access. Let's
do the same here so our gpkg's are more symetric to rpm's and
deb's and tools that look for these files there can find it.

This also provides an easy location for the user to access the
config. Considering that /boot/config-x.y.z does not always
exist (the config instalation via /sbin/installkernel depends
on layout and +/-systemd configuration).
