modification history
--------------------
01h,14dec09,pgh  Add EM_ARCH_MACHINE_x macro definition.
01g,25jul05,v_r  Updated copyright.
01f,18sep04,jn   Move towards shared code between host and target loaders
01e,12jul04,jn   Source sanitization
01d,12apr04,jn   Cleaning up header files after merge of AE loader work into
                 Base 6
01e,08mar04,pad  Renamed the relocation type R_PPC_PLT24 into R_PPC_PLTREL24
		 to match the ABI.
01d,27feb04,pad  Renamed relocation type R_PPC_SDAREL into R_PPC_SDAREL16 to
		 match ABI.
01c,31mar95,yao  added greenhill bug related definitions.
01b,24mar95,yao  updated relocation type to EABI version 1.0. rename the
		 definitions conflicted with 1.0 in draft1.1 from
		 R_PPC_XXX to R_PPC_XXX_OLD.
01a,06dec94,yao  created.
