Probably the best place to do this test is in TLUtils::setup_programs
around here (lines 1273-79):

  # check for existence of lzmadec; this determines whether the present
  # pltform is supported.  Because of conv_to_w32_path possibly adding
  # quotes, strip them away for the file test.  Since all other uses of
  # conv_to_w32_path use the result in shell commands, this is the most
  # expedient thing to do.
  (my $lzmadec = $::progs{'lzmadec'}) =~ s/^"(.*)"/$1/;
  return(-1) if (! -r $lzmadec);

Maybe adding:

  return(-2) if (! -x $lzmadec);

with return code -2 signaling 'noexec' to the installer.
