Why don't you simply use the <pkg>_EXTRA_DOWNLOADS variable? It allows
you to download additional files from the same site, which seems to be
exactly what you're trying to achieve.

LIBFOO_SITE = ftp://myftpserver.mydomain.com/libfoo/
LIBFOO_SOURCE = <one file>
LIBFOO_EXTRA_DOWNLOADS = <another file> <yet another file>

Best regards,

Thomas
