[LTP] [RFC] Showing skipped tests in results?

I think that you misunderstand how things works, the first string on
each line in the alltests file that is parsed by ltp-pan is just test
name that appears in the test result file, it does not affect anything
but that.

I guess that the easiest solution would be replacing the actuall command
that is supposed to be executed with something that just reports
skipped status.

Quick hack would be replacing these with something that just returns the
right exit value:

gzip01 gzip_tests.hs -> gzip01 exit 32

Something like this should mark the gzip01 as TCONF in test results,
would that suffice for your purpose?

This should be as easy as changing the sed command from delete to
replace in the runltp script.
