This is actually a v2 AFAIK.


The v1 was probably not from me, there were several attempts.

The parameter --disable-dependency-tracking is supposed to speed up
one-time build due to the fact that it disables some dependency
extractors that, apparently, take longer time to execute.  That is a
problem for code that is generated into builddir (especially some
specific subdirectory) because the directory it should be installed to
does not exists in VPATH and without the dependency tracking is not
created.  Generating such file hence fails with -ENOENT.  In order to
keep generating files into builddir instead of srcdir, we must create
the directory ourselves.  This should finally fix the problem that is
being fixed multiple times since its introduction in commit a9fe62037214
and let us continue with cleaning those parts of Makefiles that depend
on generating files into the srcdir rather than builddir as it should
be.

Not sure whether the last sentence is worth to be in the commit message.


I'll remove it.


And of course I forgot that when rebasing.  Fortunately this was not
hard requirement for the ACK ;-)
