It does not appear to do so.

After more testing I find that the "make replace" step deletes the files only 
some of the time.  More careful investigation shows that "make replace" has to 
be repeated before the corruption occurs.

Starting with a "good" system:

1) make in qt4-libs and qt4-tools
2) make replace in qt4-libs
no missing files at this point
3) make replace in qt4-tools (this step is probably irrelevant)
4) make replace in qt4-libs*
now there are missing include files
5) make replace in qt4-tools*
tools file restored (I'm still missing qdbus and qca2 files)
6) make replace in qt4-libs*
no missing tools files
7) make replace in qt4-libs*
tools files are missing again

* after removing .{install,replace,package}_done

I was tracking /usr/pkg/qt4/include/QtUiTools/quiloader.h in order to narrow 
down exactly where the files are deleted.  The culprit is the 
/usr/sbin/pkg_delete step (see the last line in the "make replace" output 
fragment):

===> Replacing for qt4-libs-4.6.2
WARNING: experimental target - DATA LOSS MAY OCCUR.
Creating binary package: qt4-libs-4.6.2

I was thinking that perhaps the tool files somehow become associated with the 
qt4-libs package.  That does not appear to be the case, however, as shown by 
the following pkg_info output (run just before step 7):

$ pkg_info -F /usr/pkg/qt4/include/QtUiTools/quiloader.h
Information for qt4-tools-4.6.2:                                        

Comment:

Requires:
libtool-base-[0-9]*
libXinerama>=1.0.1 
cups>=1.3.11nb3    
qt4-libs>=4.6.1nb2
...

BTW The above was done without USE_DESTDIR or PKG_DEVELOPER
