Build: disable zero length array warning

Browse Source 
We hit following build error when using gcc10:
  arch/x86/page.c:240:48: error: array subscript is outside
  array bounds of 'struct page[0][1]' [-Werror=array-bounds]

It happens with gcc10 on different Linux distributions.

Regarding the case that ACRN depends on zero length array in
sevaral places, we disable the zero length array warning by
gcc option.
