[Qt-creator] Patch: ensure that install rules for docs are generated correctly

[Ilkka Laukkanen]

Hi,

I noticed that creator suffers from the same qmake issue that I wrestled
with on another project: if you want to have installable files that are
generated at build-time, you have to ensure that the *targets* already
exist when qmake is run or install rules won't be generated in the
Makefile. In creator's case it's the .qch file that won't get installed,
unless you:

  1) run qmake
  2) make install so that the .qch file is generated
  3) run qmake *again* so that the install rules are regenerated
  4) make install so the .qch file is installed.

This patch tries to address that issue by adding a (unix scoped)
system() command in the doc/doc.pri file that creates an empty
placeholder file when qmake is run. This ensures that the install rules
are always created.

I don't know if this problem exists on other platforms.
