[Libreoffice] [PATCH] bsdtar works as fine as gnu tar

Hi,

On FreeBSD we use bsdtar (libarchive) and from my testings it works
great with libreoffice (no regression compared to gnu tar)

here is an attempt to allow checking for both bsdtar and gnu tar in
configure (against build git repository)

Hope this is ok

regards,
Bapt
