OK, but how about using an illegal instruction with free-standing environments
and abort() with hosted ones? After all, the abort() way is documented in the
GCC manual (under __builtin_trap) and IMHO, abort() would provide a better QoI
for hosted environments.

Now, concerning the warning "note: if this code is reached, the program will
abort", could "with __builtin_trap" be added so that the user could look at the
right place in the manual?
