I'm afraid that we can't do this, the problem is that we need call get_bb_vars()
to get LOG_DIR (d.getVar('LOG_DIR') doesn't work), but get_bb_vars() runs
"bitbake -e" which doesn't work when "bitbake <image> -ctestimage" since there
is a bitbake server running. We can only get BUILDDIR if we don't call
get_bb_vars(), so I think that we have the following 2 solutions:

1) Save it to /tmp/runtime-hostdump

Or:

2) Save it to BUILDDIR/runtime-hostdump

What's your opinion, please ?
