/opt/eldk-5.4 is the defualt location for the installation of the
build results.  You can of course also use this for building, but I
recopmmend against it; I usually try to keep downloads, build tree and
installation directories separated.

The default locations as used in our setup are /opt/eldk/downloads for
the downloads directory (DL_DIR variable in local.conf) and
/opt/eldk/build for the build directory (selected by the argument when
running "source oe-init-build-env").

Feel free to change these to your liking.

Best regards,
