The top-level ./configure wrapper did `cd scripts`, which is resolved
against the caller's current directory. Running it from anywhere other
than the source top (e.g. `mkdir build; cd build; ../configure`) failed
immediately with:
../configure: line 12: cd: scripts: No such file or directory
Derive the script's own location via `dirname "$0"` and cd into
"${basedir}/scripts" so the wrapper works regardless of CWD.
