From 697a7ba791fce2ffab2ed723d909a89684019e3d Mon Sep 17 00:00:00 2001
From: "Tuan M. Hoang" <tmhoang@flatglobe.org>
Date: Sun, 19 Feb 2017 17:03:33 +0000
Subject: [PATCH] main/gcc : when building gcc-java on s390x, libgcj.so
complains about undefined reference to __data_start. Using
SEARCH_FOR_DATA_START instead solved it. Credit to Andrew Haley at RedHat.
