You can't remove the (large) directory tree because you need to be able to
build old releases.

Having 'a' and 'b' trees means that you don't have replications of
unchanged files.
But arranging to alternate between them might be tricky.

What about a gcc_old tree that imports the old version from the 'gcc'
tree (probably as a vendor branch import).

The other option is (somehow) to arrange to checkout a tag for the
builds that can't use HEAD.
Having put down a branch tag (etc) before importing the new version.
