Until now, eld used to incorrectly evaluate before SECTIONS and after SECTIONS assignments both before and after the in-SECTIONS assignments. This results in incorrect liner script symbol values and incorrect layout. This patch fixes this linker script assignment evaluation order. Now, we evaluate the assignments after the SECTIONS command as part of the layout re-iteration loop in create(Script)ProgramHeaders. One of the key design change in this patch is to store AfterSections assignments with the last output section. It is required to properly evaluate the assignments when the link contains multiple SECTIONS commands. Resolves qualcomm#430 Signed-off-by: Parth Arora <partaror@qti.qualcomm.com>
