bash's configure script should report that it is checking "which library 
has the termcap functions", specifically for the tgetent symbol. It 
probes libtinfo before libncurses or libncursesw.

On your system it might be misdetected. On my linux distro, libtinfo 
does not exist, except as an alias to libncursesw.so.6 -- but the 
official Debian package for bash overrides the detection by running:

make TERMCAP_LIB="-ltinfo"
