Fix 32bit kernel builds by not using eu-stripsubmit/tizen/20130517.024101submit/tizen/20130509.184059accepted/tizen/20130520.094313

Right now 32bit kernel builds are failing because eu-strip is not
performing safe operations. In order to work around this, use objdump
as before when running a kernel build (by checking for a Kconfig file
in the BUILDIR).
