From 29d12344fb682a053de53eb08b95704cf3b67af2 Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>

Subject: [PATCH 29/35] 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]
