One can do so. The fact that this will work correctly or still make
the program crash because trapping doesn't work reliably is another
matter. In the former case[*], we win. In the latter case, there's
no change compared to the current behavior.

[*] All POSIX conforming systems should be in this case, as POSIX says
"The following signals shall be supported on all implementations" and
this includes SIGILL.
