So it's the 0 terminators from sofini.c that break things when a new linker
puts them into .init_array/.fini_array?  Just curious, I'd like to be sure I
understand what is going on here.  See
http://sourceware.org/ml/binutils/2011-01/msg00159.html

In regard to "minus crtfiles??!!!", this is exactly why those files do not have
their .ctor/.dtor sections placed into .init_array/.fini_array.  .init_array
and .fini_array don't use sentinels and obviously you don't want to try to
execute a function at 0 or -1.
