Since the new 3.2.x releases
--with-static-libs=libtalloc,libtdb,libnetapi,libaddns,libsmbclient,libsmbsharemodes,libwbclient
can't link libwbclient statically to the binaries.

$ ldd ./bin/net 
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x4001e000)
        libresolv.so.2 => /lib/libresolv.so.2 (0x4004c000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x4005f000)
        libdl.so.2 => /lib/libdl.so.2 (0x40074000)
        libreadline.so.5 => /pkg/lib/libreadline.so.5 (0x40078000)
        libncurses.so.5 => /pkg/lib/libncurses.so.5 (0x400a5000)
        libwbclient.so.0 => /pkg/lib/libwbclient.so.0 (0x400e7000)
        libc.so.6 => /lib/libc.so.6 (0x400f0000)
        /lib/ld-linux.so.2 (0x40000000)
        libtalloc.so.1 => /pkg/lib/libtalloc.so.1 (0x40207000)

Modifiying the source/Makefile, and replacing libwbclient.so with libwbclient.a solved the problem till 3.2.1, but since 3.2.2 this trick does not works any more.
