From: Kees Cook <keescook@chromium.org>
[ Upstream commit e36b70fb8c707a0688960184380bc151390d671b ]
The early boot stub for sh had UBSan instrumentation present where it is not supported. Disable it for this part of the build.
sh4-linux-ld: arch/sh/boot/compressed/misc.o: in function `zlib_inflate_table': misc.c:(.text+0x670): undefined reference to `__ubsan_handle_shift_out_of_bounds'
