Hi guys,

      I was digging for the latest information on the size cost of our
dependencies, and was interested to see things like:

      workdir/unxlngi6.pro/Dep/LinkTarget/Library/libfwklo.so.d

      contain only lots of:

/data/opt/libreoffice/master/workdir/unxlngi6.pro/CxxObject/framework/source/accelerators/globalacceleratorconfiguration.o
 :$(gb_Helper_PHONY) 
/data/opt/libreoffice/master/workdir/unxlngi6.pro/CxxObject/framework/source/accelerators/keymapping.o
 :$(gb_Helper_PHONY) 

the reason why you are seeing this is that you're a naughty person and
not running "make check", where the second make invocation would rebuild
the LinkTarget .d files.

      It seems some clever person deferred the dependency generation until an
incremental build is done (?) :-) I assume that accelerates the
straight-through build too (?).

actually it makes a full build from scratch slower, expecially on
Windows writing thousands of .d files takes several minutes.

the advantage is that you can do a partial build; with the old way of
doing things every object file in every module was built to include the
.d file even when you only want something like "make comphelper.all".
