Subject: [PATCH] Correct assertion in NIOS2 linker to allow signed 16-buit
immediate values.
PR 19405
* elf32-nios2.c (nios2_elf32_install_imm16): Allow for signed
immediate values.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Limit the
number of messages about FDE encoding preventing .eh_frame_hdr
generation.
[Romain: rebase on 2.25.1]
