"Fatal error: Cannot save core with multiple threads running" on a simple "make"

[phmarek]

see above; the problem comes from my ~/.sbclrc initializing swank.

With a --no-userinit in the Makefile QL is not initialized, and so the required libraries are not found.

How should we fix this? Include a QL stub here, or have a way to autodetect/configure the QL software directory?

I guess that --no-userinit would now make some sense.
