1;; Wrapped symbols are marked as weak for LTO to inhibit IPO. The ARM backend
2;; was previously explicitly marking the personality function as global, so if
3;; we attempted to wrap the personality function, its initial binding would be
4;; weak and then the ARM backend would attempt to change it to global, causing
5;; an error. Verify that the ARM backend no longer does this and we can
6;; successfully wrap the personality symbol.
