From 8e9d6efecdc8c42f47e3a012dee764b13c3dad59 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]
