BaseTools/AARCH64: use large code model for GCC <= 4.8
As it turns out, upstream GCC only supports the AArch64 'tiny' code
model as of version 4.9. Since the default 'small' code model requires
4 KB section alignment (which is undesirable for the XIP modules),
revert GCC 4.7 and 4.8 to using the 'large' code model instead.
