Instead of relying on kernel version to determine if the 'remove' callback for the 'bus_type' structure return an integer or void, add a compile time test to the conftest.sh script to determine this at compile time for the kernel being used. This is beneficial for working with 3rd party Linux kernels that may have back-ported upstream changes into their kernel and so the kernel version checks do not work.
