bcwc_pcie make fails (resolve_btfids) - debian 12.1 #287

Hi,

I have used firmware and module install for years on debian buster with macbook pro 11.1

I recently updated to debian 12 and if the firmware install works fine I'm stuck at the make step for bcwc_pcie

I had a script containing the different commands described on your wiki which worked perfectly on buster (it had to be replayed after OS updates). To spot any error on my side, I started from scratch by following the steps on your wiki again: the firmware installs fine (/usr/lib/firmware/facetimehd/firmware.bin) but without success for bcwc_pcie

make fails about missing resolve_btfids and I can't figure out how to fix that.
