Worth testing, if only to have a non-Guix way to illustrate the issue
for reporting upstream if necessary.

Is there a way to get the exact ASD file plus command line that is used
by the build system?

Building sbcl-numcl works fine with 1.5 and 2.0. It's only with 2.0.2
that there is this heap issue.

If it's not a Guix issue, then yes, that's the way to proceed.
