Re: [PATCH v3 0/5] efistub: convert into static library

- make sure that removals of 'static' modifiers occur in a way that doesn't
break bisect (i.e., definition + all declarations in the same patch)
- avoid ia64 breakage (which does not use the stub) by building it
conditionally
on CONFIG_EFI_STUB not CONFIG_EFI
Changes since v1:
- added patch #1 to change EFI_ERROR, it is not a result code defined by UEFI
so
it should only be returned by get_dram_base() and efi_entry()
- added a section to libstub Makefile to clean CFLAGS of stack protecter and
other options that are inappropriate for the stub
- rebased onto the UEFI Runtime Services NEON patches (re)posted earlier today

Thanks Ard, queued up for v3.17.
