From 23656d08e2055c62b09138f9330c15f088d74127 Mon Sep 17 00:00:00 2001
From: Bernd Schmidt <bernds_cb1@t-online.de>
Date: Thu, 17 Jan 2008 19:11:18 +0000
Subject: A patch from our Blackfin repository, originally from Jie Zhang. 
 This fixes a problem where the linker was trying to use the wrong symbol name
 for the init function.

Define SYMBOL_PREFIX as _ in Rules.mak for h8300, bfin, i960,
microblaze, and v850. Add -D__UCLIBC_UNDERSCORES__ in CFLAGS for targets
which define SYMBOL_PREFIX as _. Remove defines and undefs from
uClibc_arch_features.h of each target.
Add $(SYMBOL_PREFIX) to __uClibc_init when passed by ld option -init.
