tint: introduce the new tint build system with checksum verification

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.
