cras build fails on clean install of 19.10

[dantrevino]

While testing with 19.10, I did a clean build, then attempted to run the script. cras build fails with the following:

cras does not like gcc9 which ships with 19.10 - you need to install gcc8 and set env vars to use it

Thanks @flantel! I ended up using your patched version due to other issues later, and it worked great.

Thanks!
