Three stages of the new tint build system:
1) generate_core.sh extracts the core part from buildgcc script,
most importantly the checksum calculation/verification functions.
2) tintify_core.sh adds the tint-specific footer/header to the core,
such as the properties of current version including its checksum.
3) tint.sh - generated and "tintified" core script - builds a tint.
