It sure does (as it should IMHO). I use 4NT 5.0U. 
nmake -nologo:

        del thisdoesnotexist
4NT: (Sys) Systemet finner ikke angitt fil.    <<< ERROR_FILE_NOT_FOUND = 2
     0 files deleted
NMAKE : fatal error U1077: 'del' : return code '0x2'


But cmd doesn't set errorlevel. cmd /c nmake -nologo
        del thisdoesnotexist
Finner ikke C:\TEMP\tmp\thisdoesnotexist
        echo still working...
still working...

But modifying my shell-win32.conf doesn't seems to help;
The "del" command there isn't used in all places by qmake.

No. I expect the whole build of Qt5 three to break. I'm sticking to
Qt 4.8.2 that works with my shell (with some tweaking of some .conf-

PS. The 4NT docs on "ERRORLEVEL" says: 
  Various implementations of Microsoft's CMD.EXE also set ERRORLEVEL
  for some but not all internal commands. Our products attempt to emulate 
  that behavior, but...

My emphasis on "not all internal commands".

Not sure I can turn off errorlevel or OS-error codes for "del". A fix for 
me is to use:
  alias del=rm -f
