mod/file2alias: make modalias generation safe for cross compiling
Use the target compiler to compute the offsets for the fields of the device_id structures, so that it won't be broken by different alignments between the host and target ABIs. This also fixes missing endian corrections for some modaliases. Signed-off-by: Andreas Schwab <schwab@linux-m68k.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
