Maximilian Brune 7bcec7a2ef payloads/LinuxBoot: Build x86_64 with host toolchain 
Currently our coreboot toolchain cannot build the Linux kernel in case
of x86_64. It spits out the following error during build:
```

```

In order to fix it, we will default to the host toolchain in order to
build x86_64 Linux. For that we add another Kconfig that decides,
whether or not a cross toolchain is used to build Linux.
