cmake/bochs: more strict dependency handling for libfailboch_external

Browse Source 
The configure step for libfailbochs_external could be executed parallel
to other build steps, which required the files produced by the configure
step. Therefore a race-condition occurred. By giving the configure step
an explicit target name, more correct dependencies could be modeled
within bochs.cmake.
