LoongArch: vDSO: Disable UBSAN instrumentation
[ Upstream commit cca5efe77a6a2d02b3da4960f799fa233e460ab1 ]
The vDSO executes in userspace, so the kernel's UBSAN should not
instrument it. Solves these kind of build errors:
loongarch64-linux-ld: arch/loongarch/vdso/vgettimeofday.o: in function `vdso_shift_ns':
lib/vdso/gettimeofday.c:23:(.text+0x3f8): undefined reference to `__ubsan_handle_shift_out_of_bounds'
