login shell binary outside of /bin

[Basin Ilya]

Hi
I compiled bash 5.1 and installed it to /usr/local

If I try to use it as a login shell it fails to launch programs while sourcing /etc/profile. If I copy the binary to /bin it works. If after successful login I launch `/usr/local/bin/bash5 -login` again it works. If I copy the official bash4 to /usr/local/bin and try to do the initial login it fails just like bash5.

Bad:
