+Initial Package Version: 4.1.2
+Origin: Ryan Oliver (issue reported by Erik-Jan Post)
+        Rediffed against 4.1.0 by Chris Staub

+Upstream Status: N/A
+Description:
+  Removes standard_exec_prefix_2 from library search path when cross-compiling.
+  Removes both standard_exec_prefix_1 and standard_exec_prefix_2 from the gcc
+  executable search path when cross-compiling.
+
+  ie: if cross_compile = 1 in the specs file, do not
+      - do not add /usr/lib/gcc/${TARGET}/${GCC_VER} to the library search path
+      - do not add /usr/lib/gcc/${TARGET}/${GCC_VER} or
+                   /usr/libexec/gcc/${TARGET}/${GCC_VER}
+        to the executable search path
+
+  This avoids the possibility of linking in libraries from the host if they
+  exist under those directories.
