This behavior is handled by the shell (in turn typically provided by
busybox), using variable PS1.
For example, setting it to:

PS1='\u@\h:\w\$ '

will show you the username, hostname, and current directory.
The buildroot default configuration has a fixed setting, but you could
create an executable file /etc/profile.d/prompt.sh (the name 'prompt'
is arbitrary) in which you can set PS1 to the value you like.
This file will be read when creating a new login shell, via /etc/profile.

Best regards,
Thomas
