  Log:
  Add support to enable libc to be compiled in ELF format. (#ifdef __ELF__)
  In a nutshell, this macroizes the local/global symbol scoping rules
  that are different in a.out and ELF.  It also makes the i386 assembler
  stubs conform to i386 PIC calling conventions - the a.out ld.so didn't
  object, but the ELF one needs it as it implements PIC jumps via PLT's as
  well as calls.  The a.out rtld only worked because it was accidently
  snooping the grandparent calling function's return address off the stack..
  
  This also affects the libc_r code a little, because of cpp macro nesting.
