fix bug introduced by #6501

Browse Source 
( @Akien : this PR is for current HEAD only, not to be cherry-picked for 2.1.1 )

this is manual revertion of #6501 which introduced a bug that prevented
scons from detecting Mingw under Windows when MSVC was installed.
(thanks to @vnen for finding this)

AND
it fixes the actual bug that prevented scons from detecting MSVC standalone
compiler ( a confusions between ``VSINSTALLDIR`` and ``VCINSTALLDIR`` )

The freeware Standalone MSVC C++ Build Tools are available here :
