Unfortunately, the sanitizer functionality depends on a variety of GNU
extensions and headers that simply don't exist on a musl based system. Fixing
this would be a fairly complicated task, though some inspiration could be taken
from dpkg's static 'libcompat' approach of supplying equivalent functionality
that might be missing. A task for another day perhaps.
