Its certainly its reasonable, I did something like this in regexp.cc in
a number of places

%!test  # Capture replacement
%! if (!isempty(findstr(octave_config_info ("DEFS"),"HAVE_PCRE")))
%!   data = "Bob Smith\nDavid Hollerith\nSam Jenkins";
%!   result = "Smith, Bob\nHollerith, David\nJenkins, Sam";
%!   t = regexprep(data,'(?m)^(\w+)\s+(\w+)$','$2, $1');
%!   assert(t,result)
%! end

The number of places to do this however seems large... Also do we just
assume that if one sparse package in UFSparse is missing they all are or
should each test be disabled only if the specific functionality it needs
is missing? I.E. Do we support older versions of UFSparse in the tests.
If so the job becomes larger yet again to correctly disable the right
tests..
