Hi Joel,
What do you meant by dynamic loading tests?
Below is the content of config.log
----------------------START-------------------------------------------
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by rtems configure 5.0.0, which was
generated by GNU Autoconf 2.69. Invocation command line was
