toolchain-scripts: Sync the SDK/ADT values to the build system

The build system passes specific TUNE (fundamental) flag values to various
tools instead of using a shell wrapper or similar.  It is important that the
build system and ADT/SDK match the behaviors exactly, or we are likely to
have differences in the way build-system and external components are built
leading to configuration, compilation and/or run-time problems.
