releasetools/*image.sh
- Removed an "export CPPFLAGS=${FLAG}" which prevented proper settings
from the environment to be passed to the build step.
- Re-arranged variable settings at the top, so that we don't need
to evaluate the argument to vfat mkfs command anymore in
arm_sdimage.sh
- "Merged" both script for easier comparison in the future.
