Alpha has a complicated scheme by which every input object file may
be assigned to a different GOT, each of which is limited to 64k.  The
other reason this works is that variables assigned to .sdata/.sbss 
are _not_ treated differently wrt code generation.  Instead, this is
optimized via linker relaxation.

IA-64 will overflow its small data area at 22 bits.

PowerPC and Sparc do not use .sdata/.sbss.
