Exactly, that was my original thought.

You can kind of do that manually now.
Build with the -K option and when it fails, drop to the temporary
directly, source the `environment-variables` file, fix the code or calls
then proceed.

Obviously reusing cached build would be nicer.

Maybe even better would be debugger access to the daemon.  On build
error we would be dropped in the debugger in the stack frame where it
errored.  We would fix it, then continue, in the most traditional Lisp
fashion!
