fix mkinst3.test

[Ralf Wildenhues]

OK to apply?  The build path contained the string `build-power',
and thus the test failed spuriously.  I figured fiddling with
" $* " and *\ -p\ * was ugly as well (and error-prone if you
allow spaces in directory names!), so I chose to rather do it
The Right Way[tm].

Cheers,
Ralf

        * tests/mkinst3.test: Fix `mkdir' wrapper to not be confused
        if ``pwd`' contains the string `-p'.
