libgpg-error: import newer version from upstream

A fix went into upstream for amd64 multilib installs which we need:
`gpg-error-config` likes to display -L/usr/lib64 when cross-compiling.

BUG=chromium-os:20636
TEST=`emerge-x86-generic libgpg-error`; `/build/x86-generic/usr/bin/gpg-error-config --libs` shows correct output (no -L flag)
TEST=`emerge-x86-generic libgcrypt` still works
TEST=`emerge-amd64-generic libgpg-error`; `/build/amd64-generic/usr/bin/gpg-error-config --libs` shows correct output (no -L flag)
TEST=`emerge-x86-generic libgcrypt` now works

+Subject: [PATCH] gpg-error-config: handle /usr/lib64, /lib64 just like
+ /usr/lib and /lib
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Distributions such as Gentoo Linux use /usr/lib64 for system libraries on
+multilib setups, so in those cases, ignore the libraries as well.
