mk: prevent removing dependency files

GNU Make since version 4.4 started to remove *.d files, apparently
because it considers them intermediate. This is a regression, fixed in
version 4.4.1 - 95c2db7b ("[SV 63484] Force included makefiles to be
explicit"). It causes issues with rebuilding sources that had their
include files changed. To prevent this, use the .NOTINTERMEDIATE special
target, which was also introduced in GNU Make 4.4.
