Subject: [PATCH] [ELF] - Do not create huge garbage files on section offset
 overflow.

Patch changes behavior to not try open the output
file if we already know about error.

That is not just cleaner, but also fixes nasty behavior of linker that
could create huge temporarily files under certain conditions.
