Restore SIGFPE handler after initializing PL/Perl.
Perl, for some unaccountable reason, believes it's a good idea to reset
SIGFPE handling to SIG_IGN. Which wouldn't be a good idea even if it
worked; but on some platforms (Linux at least) it doesn't work at all,
instead resulting in forced process termination if the signal occurs.
Given the lack of other complaints, it seems safe to assume that Perl
never actually provokes SIGFPE and so there is no value in the setting
anyway. Hence, reset it to our normal handler after initializing Perl.
