Ben Gras e83f7ba2c9 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
