setup: Use machine-specific build directories by default

bitbake can struggle to cope with switching machine configurations in
the one build directory, so default to using machine-specific build
directories.

It's recommended that the following be added to your .profile
to provide a common location for bitbake data caches:

```
BB_ENV_EXTRAWHITE="SSTATE_DIR DL_DIR"
SSTATE_DIR="/var/cache/bitbake/sstate-cache"
DL_DIR="/var/cache/bitbake/downloads"
export BB_ENV_EXTRAWHITE SSTATE_DIR DL_DIR
```
