I am new to this mailing list, so please feel free to correct me if I
have posted the reply incorrectly.
Thank you for your feedback. Yes, I have used this arm-elf-gcc
compiler for all my other projects, but they are only small
applications, smaller than curl.

Also the error, "compiler cannot create executables", I do not
understand. It does not say why it cannot...
I have read trough the config.log. Can I post it here for you to see?

Bernard E,
