But it is aimed at the complete samba suite, whereas I really only want smbclient. In the past I've been able to cut it down reasonably to just the smbclient. But in the last year, changes to samba and the Yocto samba package have made it more difficult to cut it down to a minimal smbclient.

It probably still won't be small, but you can try:

(untested)

./configure --nonshared=binary=smbclient

This would give you a single static binary.

I did try and to work to have a Samba build that then used global
optimization and linker flags to remove unused code, but those patches
never went anywhere.  They were posted to samba-technical under a
thread title of 'making samba small again' a couple of years ago.
