It seems the libtalloc installed in your host pc is too old.

I have libtalloc.2.1.10 and the symbol is there:
$ strings /usr/lib/libtalloc.so.2.1.10 | grep _talloc_zero_array

Please make sure the libtalloc in your system has that symbol in, 
otherwise update it to a newer version. You can check through git log to 
see when was that symbol added, and infer from that which minimum 
libtalloc verison you need. I guess we should be checking that during 
configure time in osmocom-bb.
