Absolute relocs in EFI stub w/ tracing options

[Will Deacon]

Hi Ard,

Just to say that I hit some ABS64 relocs in the stub today when compiling
with all of the "tracer" options enabled (in particular, you need to
enable CONFIG_PROFILE_ALL_BRANCHES).

Looks like that code #defines if :/

Log below.
