uClinux support in LTP has been broken for years and nobody seemed to
really care. I even tried to ask if there is someone interesting in
running LTP on uClinux on the uClinux mailing list but it seems that
even the list is basically dead at this point. So for a last year or so
we are slowly getting rid of the uClinux specific bits from the codebase
in order to simplify the LTP maintenance. You are free to step up and
restore uClinux support in LTP if you have time for that but unless that
happens we will continue to stage it out.
