lib/ubsan.c: fix gcc-10 warnings
The latest compiler expects slightly different function prototypes for the ubsan helpers: lib/ubsan.c:192:6: error: conflicting types for built-in function '__ubsan_handle_add_overflow'; expected 'void(void *, void *, void *)' [-Werror=builtin-declaration-mismatch] 192 | void __ubsan_handle_add_overflow(struct overflow_data *data, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ lib/ubsan.c:200:6: error: conflicting types for built-in function '__ubsan_handle_sub_overflow'; expected 'void(void *, void *, void *)' [-Werror=builtin-declaration-mismatch] 200 | void __ubsan_handle_sub_overflow(struct overflow_data *data, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ lib/ubsan.c:207:6: error: conflicting types for built-in function '__ubsan_handle_mul_overflow'; expected 'void(void *, void *, void *)' [-Werror=builtin-declaration-mismatch] 207 | void __ubsan_handle_mul_overflow(struct overflow_data *data, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ lib/ubsan.c:214:6: error: conflicting types for built-in function '__ubsan_handle_negate_overflow'; expected 'void(void *, void *)' [-Werror=builtin-declaration-mismatch] 214 | void __ubsan_handle_negate_overflow(struct overflow_data *data, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ lib/ubsan.c:234:6: error: conflicting types for built-in function '__ubsan_handle_divrem_overflow'; expected 'void(void *, void *, void *)' [-Werror=builtin-declaration-mismatch] 234 | void __ubsan_handle_divrem_overflow(struct overflow_data *data, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Change the Linux implementation to match these, using a local typed pointer.
