I can't reproduce this. A bash compiled without readline and SYS_BASHRC
defined behaves the same as a version compiled with readline included and
SYS_BASHRC defined.

The answer differs with the invocation circumstances, since the bash
behavior with loading startup files depends on how it is invoked.
If you want to keep bash compiled with SYS_BASHRC defined, and you
control the contents of SYS_BASHRC, you might want to change it so
it will not continue if a particular environment variable is defined:
if [ -n "$NOSYSBASHRC" ];then
return
fi
[rest of /etc/bashrc goes here]
