patch grub EFI setjmp in IA32

[bibo,mao]

hi,
  In IA32 application function  parameter is passed on stack but not register,
on grub_setjmp funciton, env is pushed on stack, but not eax register.Caller is
responsible to push parameter on the stack and after function call pop the 
stack.

Here is the patch for setjmp.S in IA32 EFI, any suggestion is welcome.

Thanks
bibo,mao
