Subject: [PATCH] ld: always warn about textrels in files

textrels are bad for forcing copy-on-write (this affects everyone), and for
security/runtime code generation, this affects security ppl.  But in either
case, it doesn't matter who needs textrels, it's the very fact that they're
needed at all.

Subject: [PATCH] gold/ld: add support for poisoned system directories

This is based on the old CodeSourcery patch written by Joseph Myers to add
support to the link for detecting & rejecting bad -L paths when using a
cross-compiler.  The differences here:
* The command line flags are always available.
* We can turn on & off the warning via the command line.
* The configure option controls the default warning behavior.
* Add support for gold.

It is not currently upstream, nor has it been submitted at all.  There are
no plans to do so currently either.

BUG=chromium:488360
TEST=`cbuildbot chromiumos-sdk` passes  # tests arm/amd64/mipsel/x86
TEST=`cbuildbot panther_moblab-full whirlwind-release` pass
TEST=`cbuildbot {x32,arm64}-generic-full` has no new failures
TEST=x86_64-cros-linux-gnu-ld throws warnings when using -L/lib (gold & bfd)

Subject: [PATCH] gold/ld: enable gnu hash by default

Glibc first added .gnu.hash support to glibc-2.5 (released 29 Sep 2006),
and gold was first released after that.  Let's default the gnu hash style
to the new "gnu" rather than the classic sysv.

gold/:
2012-02-03  Mike Frysinger  <vapier@gentoo.org>

	* options.h (General_options): Change default to gnu for hash_style.

Subject: [PATCH] libiberty: install PIC version of libiberty.a

This will install a PIC version of libiberty.a by overwriting the non-PIC
version of libiberty.a while compiling.  We do this because there is no
shared version of libiberty for random apps to link against which means if
someone wants to use this in a shared library or PIE, they're out of luck.
It's arguable whether people should be able to use this in a shared lib,
but usage in PIE should be fine.  You could argue that this penalizes the
non-PIE users, but the counter point is that people using this library in
general are fairly low, and we'd rather have things work for all of them.

Subject: [PATCH] opcodes: link against libbfd.la for rpath deps

The reason opcodes doesn't link against libbfd.la is to workaround a
libtool bug where it uses installed -L paths ahead of DESTDIR paths.
The downside is that the library itself lacks rpath tags to find the
right version of libbfd.so.

Since Gentoo has patched the libtool bug for a while, we don't need
the workaround.  Use the .la file so we get the rpath tags.
