BTW, keeping the original, pessimistic approach to getting the valueset for
'RU?N?PATH' and 'NEEDED', this could potentially be greatly simplified by taking the
last value (NF) instead, trimming the brackets, if present, with greadelf on 'NEEDED'.

Also, greadelf's '-W' seems only useful for long section names on SunOS, making
no difference with regard to paths as used here... does it really make any difference
on other platforms? This could simplify things further.
