Those are temporary files, truncated at page boundary.

	$ stat -c %s XXX.pata_sil680.mod.o.cmd
	12288

I tried to fix this by inserting shell 'trap' directive but it failed
somewhere else.

	cmd_and_fixdep =                                                     \
        $(cmd);                                                              \
        scripts/basic/fixdep $(depfile) $@ '$(make-cmd)' > $(dot-target).cmd;\
        rm -f $(depfile)
