From 4de00af67b57b5440bdf61ab364ad959ad0aeee7 Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Fri, 29 Mar 2013 09:24:50 +0400
Subject: [PATCH] Define GLIBC_DYNAMIC_LINKER and UCLIBC_DYNAMIC_LINKER
 relative to SYSTEMLIBS_DIR

This patch defines GLIBC_DYNAMIC_LINKER and UCLIBC_DYNAMIC_LINKER
relative to SYSTEMLIBS_DIR which can be set in generated headers
This breaks the assumption of hardcoded multilib in gcc
Change is only for the supported architectures in OE including
SH, sparc, alpha for possible future support (if any)

Removes the do_headerfix task in metadata

Signed-off-by: Khem Raj <raj.khem@gmail.com>

Upstream-Status: Inappropriate [OE configuration]
