build-source-libs.sh: drop Perl dependency

Browse Source 
Instead of using Perl to get the absolute path due to readlink -f
implementations differing behaviour use realpath. Since the inclusion
into coreutils this should be a valid alternative.

Also check for [[:space:]] instead of only \s as if that one is an issue
the others are as well.
