From ec8eda419a54674a0d326ea25bd9c440cd059065 Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Thu, 23 Jun 2011 12:21:21 +0300 Subject: toolchain: add user defined target LDFLAGS options Allow the user to specify additional options for the target LDFLAGS. I use this to pass the -te500v2 option to the linker, when using the CodeSourcery toolchain for PowerPC. This chooses the correct CRT for e500 hard float. Otherwise I get errors like undefined reference to `_save32gpr_31' undefined reference to `_rest32gpr_31_x' at final link time.
