[RFC PATCH 11/17] efi: libstub: Ignore relocations for .discard sections

[Julien Thierry]

EFI stub cannot have absolute relocations in sections affecting the
execution flow. However, for sections that get discarded at link time,
it doesn't really matter if they have absolute relocations.

Ignore the relocation associated with such sections.
