Support: OpenBMC build failed at bmcweb (commit: 029f4aada38f4b041b5a171c2e112a267cee3b7f)

[Bremenpl]

Hi Patrick,
Following your feedback, I started of with cutting the no of cores 
available to the VM by half (now a total of 8 instead of 16)- the build 
then succeded. Thank you very much for help.

I will update the gcc version now and rerun the build still.
