We could avoid needing to pass by hand some alternative “ldd” tool
by always using ”readelf”, which works for any ELF file (no matter
the target architecture) and does not try to run any code. That
would make this “ldd” parameter to the BundleCreator unnecessary.

Something like this gets you the list of shared objects needed:

   readelf -Wd <file> | \
     awk '$2 == "(NEEDED)" { print substr($5, 2, length($5)-2) }'

The output will only include direct dependencies of “<file>”, so one
needs to run the same command recursively on each listed object, until
no more objects are added to the set. I have some shell script around
that does just that and also takes into account the DT_RUNPATH entries
from the ELF dynamic section—let me know if you are interested and I
can share it.
