Actually, if you follow the more_control hint, you don't even make install
as root. But not building as root is at least a start. This issue is
proof. There ARE hackers (well, probably just a script kiddie in this
case) too stupid to do more than add an exploit (probably not written by
the kiddie) to a makefile. A moderately competent hacker would have put
exploit code into the actual sshd and/or ssh binary. But the fact that
more severe threats do exist does not justify ignoring the lesser evils.
That would be just like saying that having a root password is pointless if
people can boot a machine with a floppy. Having a root password protects
against many attacks by wanna-be hackers (i.e. the average student) and in
a lot of environments these are the only attacks you're worried about
99.9% of the time.
An optimist thinks that this is the best possible world.
A pessimist fears that this is true.
