The use of the name tmpdir in the tests

[Ruud van der Pas <ruud.vanderpas@oracle.com>]

Hi team,

This is an absolute detail, but as I am working on the test suite
for gprofng, I noticed the use of a directory called "tmpdir".

I count about 155 .exp files across binutils that use it:

$ grep -sw tmpdir `find . -name "*".exp -print` | awk 'BEGIN {FS=":"} {print $1}' | uniq | wc
    155     155    6000
$

The thing is that in the case of gprofng at least, this is far from
a temporary directory. It is going to contain the generated experiment
data that is crucial for troubleshooting in case of a failure.

Of course we could place those experiments elsewhere, but my idea
was to give tmpdir a more meaningful name.

Are there any objections against doing so? For example, will 
certain scripts fail?

If not, any suggestion what would be a good name? I'm not that
creative so don't get any further than "results" or "expresults"
and am definitely open to suggestions.

Kind regards, Ruud
