Dear Cassio,
the problem you report looks very similar to Issue 62 [1], which I
reported a couple months ago.
This timeout on start up would also explain why the KeyboardInterrupt
nondeterministically occurs at different code locations and sometimes
occurs not at all.
I will try out your suggestion to see if it also resolves the issue that
I reported on the qemu virtual machine.
Thanks for reporting the problem and the solution to it.
To your second point:
The "core-image-ros-roscore" image only provides the packages to start
and run roscore.
However, if you have a look at the core-image-ros-roscore.bb file, you
can extend that image simply by adding more packages, e.g., rosrun,
rosbash and your own ROS packages, to IMAGE_INSTALL.
Then your image should have those packages installed as well. Please
report if some of them still have missing runtime dependencies. We have
not tested all of the ROS packages in isolation and might have missing
some dependencies.

Dear Lukas and Víctor
Error ocurred when I tried to run roscore. The process could not
contact master, as can be seen below:

KeyboardInterrupt
So I fixed the error increasing the _TIMEOUT_MASTER_START = 10.0
#seconds from python2.7/site-packages/roslaunch/launch.py to 15.0 seconds.
About the rosrun and rostopic, how can I run some executable like
Publisher and Subscriber example without it? Either am I doing
something wrong? I've done bitbake core-image-ros-roscore, but there
is no rosrun and rostopic, for example. Have you done recipes for that
on meta-ros?
I was taking a look on Víctor's tutorials and attempt do provide a
recipe from my issues, but I have no "opkg install *.ipkg" on my
board. I was reading how to bitbake some image to be able to use that,
but I do not have answers yet
