In principle, yes, but I'd think it might be more useful if we add
support for loading modules via dlopen (under linux this already works
but I'd expect RTEMS' variant to differ; in particular I'm using dlinfo
and dl_iterate_phdr, i.e., some sort of inspection is required).

Some of them (libtecla) can be configured away (but it's not a good idea
since it affects the user experience). All of the libraries should have
benign licensing.


I started adding these to the RSB as add-on libraries. There is a ticket
which captures my progress.

We need to be careful about the dependencies required to build RTEMS
itself. This may be better as an RSB kit.
