R CMD check on Win fails to detect failed installations (PR#6790)

I just post it not to forget - will try to contribute a fix.

Example: CDNmoney_2003.9-2.tar.gz (in the archives section of CRAN)
[There is another problem here I'll address separately.]

If running solely,
   R CMD check CDNmoney
fails to detect a failed installation on Windows. Instead, it reports:
* checking whether package 'CDNmoney' can be installed ... OK

Of course, the check fails later, but with some meaningless error messages.


The repository maintainer's approach works (i.e. detects the problem):

   R INSTALL CDNmoney > install.log 2>&1
   R CMD check --install="check:install.log" CDNmoney
