+The powerpc assembler can generate .PPC.EMB.apuinfo sections in some 
+circumstances.  These originate, I think, from the old e500 ABI; in 
+any case, they are only defined for 32-bit ABIs, and there is a 
+significant amount of code in bfd/elf32-ppc.c to handle them 
+appropriately, none of which is in elf64-ppc.c.  However, the 
+assembler can generate them when building 64-bit code for processors 
+such as e5500 (which uses PPC_OPCODE_E500MC).  In such circumstances, 
+they get generated as PROGBITS rather than NOTE sections, which 
+reportedly can cause problems in a Linux kernel build. 
+
+Since these sections are only defined in 32-bit ABIs, I think it's 
+most appropriate to avoid generating them for 64-bit output, which 
+this patch does.
