flang actually takes much longer to build on our arm64 runners than they do on the x86_64 ones -- likely because the x86_64 runners have more RAM. Let's try to fix that by limiting the number of concurrent link jobs spawned during the build. We do this by setting `LLVM_RAM_PER_LINK_JOB`, but this requires using `ninja` to build.

I think this made it slower? Taking 6-7 hours now. Previous was 2-3 hours. |

Yea, probably. Should revert. |
