Improve toolchain caching

Instead of putting full copy of toolchain to every build directory
(/build/<release_or_build>/) create a single copy of it in
/build/toolchains/<toolchain_id> and symlink to it through a
/build/<release_or_build>/toolchain synlink

Also clean up some dead code that is not used anywhere.
