c7e1c58fac binutils: fix xtensa gas segfault with --text-section-literals
Building libgcc with TARGET_ABI flags results in assembler segfault on
xtensa, because code in sections .init and .fini emits literals w/o
.literal_position directive. This patch turns the segfault into assembly
error.

384c919321 binutils: fix xtensa ld bug triggered by --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.

b5997f852e binutils/2.23: add patch to warn about unsafe library paths
This commit adds a patch to binutils borrowed from CodeSourcery/Yocto
that warns about unsafe library paths (i.e /usr/lib, /usr/local/lib,
etc.). The patch was adapted to binutils 2.23, and modified to support
the BR_COMPILER_PARANOID_UNSAFE_PATH environment variable to error out
instead of just warn when unsafe paths are used. Even though erroring
out can be chosen by passing --error-poison-system-directories, we are
not sure this option in LDFLAGS will always be passed, so having an
environment variable guarantees it will always be passed, and also
allows to have an identical behavior to the external toolchain
wrapper.

c09b2bfaea binutils: drop *.texi* hunks from xtensa trampolines patches
Rebuilding as.info with makeinfo version 5.2 results in a build error,
even with pristine binutils source. Dropping hunks that change *.texi*
files avoids documentation rebuild.
