[LTP] [PATCH] ltp-aiodio: help aiodio test work normally

[Cyril Hrubis <chrubis@suse.cz>]

Hi!

> due to they have unfixed path name. Before we run aiodio test, we
> need to create some files (e.g. junkfile), and give it to the tests.
> But current cmdfiles use too many $TMPDIR and aiodio.$$ things, e.g:

> TMPDIR is a directory created by `mktemp ${TMPBASE}/ltp-XXXXXXXXXX`,
> it's not a fixed path. The aiodio.$$ is also can be sure before

I do not like this solution. I think that we should instead fix the
scripts. I think that the runltp should just export TMPDIR if it was
passed on commandline and it should be the resposibility of the caller
to set up a temporary directory somewhere in /tmp in that case.
