btrfs-progs: build: omit unnecessary -MD flag
According to gcc(1), "-MD is equivalent to -M -MF file, except that -E is not implied." Since the rule in the Makefile is just generating dependency file and not building object file, it is no use to have "-MD" here. Also, it's overridden and conflicting with the following "-MM" flag. I guess we can drop it. Signed-off-by: Naohiro Aota <naohiro.aota@wdc.com> Signed-off-by: David Sterba <dsterba@suse.com>
