sh: Fix build with CONFIG_UBSAN=y

Browse Source 
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'
