The message you get when configuring is fine.  What normally is found in libgloss
is already within newlib for arm-elf so target-libgloss is not built.  The message is
just telling you that.

I would suggest you specify an absolute path to the configure script rather than
a relative path.

You are getting an assembler error when compiling.  There is no newlib file:
reading.open nor is it referenced by any newlib code.

You should try posting to the gcc, binutils, and Cygwin mailing lists.  Perhaps
someone will recognize the problem.  IIRC, there is an
environment variable you can set when building under Cygwin: "export MAKE_MODE=unix"
 
You might also want to consider setting up a single source tree to make the build
much easier.  See:

The message above can be ignored.
