/* $NetBSD: crt0.S,v 1.3 2011/07/01 02:59:05 joerg Exp $ */
switch to netbsd csu . file- and functionality-compatible with previous situation (FreeBSD csu) (with a crt1.o -> crt0.o symlink in /usr/lib) . harmonizes source with netbsd . harmonizes linker invocation (e.g. clang) with netbsd . helpful to get some arm code in there for the arm port project
