Martin,

  You won't find the Linux crt1.o in newlib.

  Newlib was initially intended only to support embedded platforms.  Other than
the Cygwin project, no native platform OS's were supported - the thought being that there
were already much more robust native C libraries out there such as glibc.

  Werner Almesberger has been doing work to add Linux support to newlib.
See ftp://icaftp.epfl.ch/pub/people/almesber/misc/newlib-linux/ for further details.
