Fix 'Calculating hash...' message

Right now I get

Calculating hash of toolchain in vs2013_files. Please wait...
Calculating hash of toolchain in vs2013_files. Please wait...
Calculating hash of toolchain in vs2013_files. Please wait...
Calculating hash of toolchain in vs2013_files. Please wait...
Calculating hash of toolchain in vs2013_files. Please wait...
Calculating hash of toolchain in vs2013_files. Please wait...

which isn't very informative (or at least a bit confusing as to why it's
doing the same thing 6 times).
