/* Force a reference to bring in EFI support from the library */
/*
* Normally, efi.o from libefi.a would be brought in due to a function we call
* there that's defined there. However, none of its functions are callable from
* here since it just adds words to the FORTH environment or implement those
* words. So, add a reference to a symbol in efi.o to force it to be be brought
* in so the init function there gets added to the "compile" linker set happens
* correctly.
*
* This assumes there's no global analysys that notices dummy1 isn't used
* anywhere and tries to eliminate it.
