New Issue: Ubuntu build giving conftest errors during qthreads build

When upgrading the Computer Language Benchmarks Game website to use Chapel 1.24.0, Isaac reported that he received errors of the form:

Sorry, the application conftest has stopped unexpectedly.

This problem report applies to a program which is not installed any more. (/opt/src/chapel-1.24.0/third-party/qthread/build/linux64-x86_64-native-gnu-none-flat-jemalloc-bundled/conftest)

when building. This did not seem to affect the result (in that he was still able to compile and run Chapel programs), but is a bit disconcerting all the same.
