Here's what I got with
echo datadir is $datadir
eval datadir=$datadir
echo datadir is $datadir
eval datadir=$datadir
echo datadir is $datadir
in configure.ac.
Output:
datadir is ${datarootdir}
datadir is ${prefix}/share
datadir is NONE/share
That NONE is a problem. Maybe if you specify a value for datadir
explicitly it will work.
The idea was to loop with the eval's until a fixed point was reached.
The answer appears to be you can do what you want only with difficulty.
