C++ objects built as PIC use offsets to encode FDE structures. As a result C++ exception handling doesn't work correctly on xtensa-uclinux. Don't use PIC by default on xtensa-uclinux. gcc/ 2018-11-07 Max Filippov Backport from mainline 2018-11-05 Max Filippov * config/xtensa/uclinux.h (XTENSA_ALWAYS_PIC): Change to 0.
