Brandon Bergren 9411e24df3 [PowerPC] kernel ifunc support for powerpc*, fix ppc64 relocation oddities.
This is a general cleanup of the relocatable kernel support on powerpc,
needed to enable kernel ifuncs.

 * Fix some relocatable issues in the kernel linker, and change to using
   a RELOCATABLE_KERNEL #define instead of #ifdef __powerpc__ for parts that
   other platforms can use in the future if they wish to have ET_DYN kernels.

 * Get rid of the DB_STOFFS hack now that the kernel is relocated to the DMAP
   properly across the board on powerpc64.

 * Add powerpc64 and powerpc32 ifunc functionality.

 * Allow AIM64 virtual mode OF kernels to run from the DMAP like other AIM64
   by implementing a virtual mode restart. This fixes the runtime address on
   PowerMac G5.

 * Fix symbol relocation problems on post-relocation kernels by relocating
   the symbol table.

 * Add an undocumented method for supplying kernel symbols on powernv and
   other powerpc machines using linux-style kernel/initrd loading -- If
   you pass the kernel in as the initrd as well, the copy resident in initrd
   will be used as a source for symbols when initializing the debugger.
   This method is subject to removal once we have a better way of doing this.
