Adds two new checks for runsuite error detection:
- Look for CMake 3.x failure to generate (separate from config: cause of regression here)
Tested: ====> FAILURE in arm-debug-internal-64 <==== arm-debug-internal-64: **** pre-build configure errors ****
- Look for failure in runsuite scripts themselves.
Tested by removing fix for #1 (closed): ====> FAILURE in runsuite script itself <==== CMake Error at suite/runsuite_common_post.cmake:119 (file): file failed to open for reading (No such file or directory): build_suite/xml:results/___arm-debug-internal-64___Experimental___XML___Build.xml Call Stack (most recent call first): suite/runsuite.cmake:545 (include)
Fixes #4312 (closed)
