aix: FAT libraries: test native compiler mode directly
The FAT libraries config fragments need to know which library is native
and which is a multilib to choose the correct multilib from which to
append the additional object file or shared object file. Testing the
top-level archive is fragile because it will fail if rebuilding. This
patch tests the compiler preprocessing macros for the 64 bit AIX specific
__64BIT__ to determine the native mode of the compiler in MULTILIBTOP.
