Subject: [PATCH] Revert "PR24311, FAIL: S-records with constructors"

This reverts commit ebd2263ba9a9124d93bbc0ece63d7e0fae89b40e.

Revert this patch since it prevent booting a sh4 system under
Qemu as reported on the Binutils mailing list [1].
This commit is not related to sh4, it's weird that it is the
only affected architecture.
