[oe] smb* tools larger than expected

[Jaya Kumar]

Hi OE friends,

I noticed my rootfs is filled with large smb* binaries. Investigating further:

At first I thought maybe these binaries were getting statically
linked, but that doesn't appear to be the case.

Looking at that list, it seems .rodata is massive, about 1MB. I don't
know enough to know why that could be the case. Is there something I
can do to get the samba package to be much smaller?

Thanks,
