To be more precise: You could actually drop the `if [ -x
"$$SAGE_LOCAL/bin/gcc" ]; then ...`, because such race conditions could
happen with "non-Sage" GCCs as well, and because of what you said above
(and because building these spkgs serially doesn't significantly increase
the overall build time).
