Revert "Parallelize depend file generation" This reverts commit d5b6ec450fde069a4e64569b0eb7e4fcb3b96e83. parallel depend ddc does not significantly speed up compilation, intermediately generated .ddc files can cause problems if compilation is interrupted unexpectedly Signed-off-by: xuxin19 <xuxin19@xiaomi.com>
