Running qmake fails if build directory cannot be created

Steps to reproduce:

• have QC's sources from git repository (I've tested 3.2 branch) - the parent directory of the repo must not be writable by the current user
• open the project from inside QC and assign a valid kit
• try to build

Expected result:

• if the project build fails an issue should pop up inside the Issues pane

Current result:

• no issue is listed inside Issues pane
• Compile Output pane must be checked to figure out what's wrong
  • Compile Output contains strange misleading paths that do not exist (due to the issue of not being able to create the build directory and change to it) [see attached log]
