Now that we have switched to binutils 2.27 as the default binutils
version, it's time to get rid of binutils 2.25. So this commit remove
the 2.25 version choice, the hash file entry, the patches, and adds a
Config.in.legacy option.

-Subject: [PATCH] Fix trampolines search code for conditional branches
-
-For conditional branches that need more than one trampoline to reach its
-target assembler couldn't always find suitable trampoline because
-post-loop condition check was placed inside the loop, resulting in
-premature loop termination. Move check outside the loop.
-
-This fixes the following build errors seen when assembling huge files
-produced by gcc:
-    Error: jump target out of range; no usable trampoline found
-    Error: operand 1 of 'j' has out of range value '307307'

-Subject: [PATCH 1/4] xtensa: optimize check_section_ebb_pcrels_fit
-
-The original check_section_ebb_pcrels_fit algorithm checks that text
-actions proposed for current EBB are OK for every relocation in a
-section. There's no need to check every relocation, because text actions
-for EBB can only change size of that EBB, thus only affecting
-relocations that in any way cross that EBB. In addition EBBs are
-iterated in ascending order of their VMA, making it easier to track
-relevant relocations.
-
-Introduce a structure that can track relocations that cross the range of
-VMAs of EBB and use it to only check relocations relevant to current EBB
-in check_section_ebb_pcrels_fit.
-It takes O(N log N) operations to build it and O(N) operations to move
-current EBB VMA window through its entire range, where N is the number
-of relocations in a section. The resulting complexity of
-compute_text_actions is thus reduced from O(N^2) to O(N log N + N * M),
-where M is the average number of relocations crossing each EBB.

-Subject: [PATCH 2/4] xtensa: optimize removed_by_actions
-
-The function removed_by_actions iterates through text actions to
-calculate an offset applied by text actions to a given VMA. Although it
-has a parameter p_start_action that allows for incremental offset
-calculation, in many places it's used with p_start_action explicitly set
-to the first action. After the first relaxation pass when the list of
-text actions is finalized, an array of offsets sorted by VMA may be used
-to speed up this function.

-Subject: [PATCH] xtensa: optimize trampolines relaxation
-
-Currently every fixup in the current segment is checked when relaxing
-trampoline frag. This is very expensive. Make a searchable array of
-fixups pointing at potentially oversized jumps at the beginning of every
-relaxation pass and only check subset of this cache in the reach of
-single jump from the trampoline frag currently being relaxed.

-Subject: [PATCH] xtensa: fix localized symbol refcounting with --gc-sections
-
-elf_xtensa_gc_sweep_hook doesn't correctly unreference symbols that were
-made local, that results in link failure with the following message:
-
-  BFD (GNU Binutils) 2.24 internal error, aborting at elf32-xtensa.c line
-  3372 in elf_xtensa_finish_dynamic_sections
-
-elf_xtensa_gc_sweep_hook determines symbol reference type (PLT or GOT) by
-relocation type. Relocation types are not changed when symbol becomes
-local, but its PLT references are added to GOT references and
-plt.refcount is set to 0. Such symbol cannot be unreferences in the
-elf_xtensa_gc_sweep_hook and its extra references make calculated GOT
-relocations section size not match number of GOT relocations.
-
-Fix it by treating PLT reference as GOT reference when plt.refcount is
-not positive.

-Subject: [PATCH] xtensa: fix signedness of gas relocations
-
-Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
-offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
-substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
-8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
-directive. Revert this part and add test.

-Subject: [PATCH] xtensa: fix .init/.fini literals moving
-
-Despite the documentation and the comment in xtensa_move_literals, in
-the presence of --text-section-literals and --auto-litpools literals are
-moved from the separate literal sections into .init and .fini, because
-the check in the xtensa_move_literals is incorrect.
-
-This moving was broken with introduction of auto litpools: some literals
-now may be lost. This happens because literal frags emitted from .init
-and .fini are not closed when new .literal_position marks new literal
-pool. Then frag_align(2, 0, 0) changes type of the last literal frag to
-rs_align. rs_align frags are skipped in the xtensa_move_literals. As a
-result fixups against such literals are not moved out of .init.literal/
-.fini.literal sections producing the following assembler error:
-
-  test.S: Warning: fixes not all moved from .init.literal
-  test.S: Internal error!
-
-Fix check for .init.literal/.fini.literal in the xtensa_move_literals
-and don't let it move literals from there in the presence of
---text-section-literals or --auto-litpools.
-
-2016-02-17  Max Filippov  <jcmvbkbc@gmail.com>

-       * config/tc-xtensa.c (xtensa_move_literals): Fix check for
