Look at the example Makefile provided.  You'll see that we use our own
startup and library files (-nostdlib), not "crt0.o" and friends.

If you're using the tools from a command line, another way to see how
applications are built is by building a test.  For example, assuming
that your build/install tree is "arm_test" and you've installed eCos
version 'VVV':         (VVV would be something like v1_3_13)

  % cd arm_test
# build eCos kernel library
  % make
# create a test
  % make -C kernel/VVV/src tests TESTS=tests/tm_basic

This will create the kernel 'tm_basic' test, with the result ending up
in the directory "install/tests/kernel/VVV/tests/"
