# boot, hence cannot depend on the C++ standard library, and must only introduce
# minimal symbols into dependent targets. As such, these libraries need to be
# static libraries rather than source sets, as we need the Unix librarian
# algorithm to apply so that only object files corresponding to the used
# functions will be linked to the final binary.
