commit d929f627aba264e63cf779cd4ca51af97b076445
Author: Natanael Copa <ncopa@alpinelinux.org>
Date:   Tue Sep 28 09:45:17 2010 +0000

    Submitted By:            Kevin Day <thekevinday AT gmail DOT com>
    Date:                    2008-12-19
    Initial Package Version: 4.3.2
    Upstream Status:         Not submitted
    Description:             Why not just be able to define the prefix of the dynamic linker instead of hardcoding it..
    This includes the --nostdinc patch as well, so think of this as a specs-3 patch
    This also allows for specifying the dynamic-linker as well
