Log:
  Print an error message in efi_main.c if we can't allocate memory for the heap
  
  With the default Qemu parameters, only 128MB RAM gets given to a VM. This 
causes
  the loader to be unable to allocate the 64MB it needs for the heap. This 
change
  makes the cause of the error more obvious.
