Spun up a RH 7.3 instance and tried the compile and got the same error.
It then rang a bell and I went back to this:

http://raghavt.blogspot.com/2015/01/configuring-automatic-failover-using.html

"/lib64/libldap_r-2.4.so.2: undefined reference to `ber_sockbuf_io_udp'
collect2: ld returned 1 exit status
make: *** [repmgrd] Error 1

To fix, find the checking library in /lib64/libldap_r-2.4.so.2.

[root(at)localhost repmgr-2.0]# cd /lib64/
[root(at)localhost lib64]# ls -l libldap*
lrwxrwxrwx. 1 root root 20 Dec 8 09:23 libldap-2.4.so.2 ->
libldap-2.4.so.2.5.6
-rwxr-xr-x. 1 root root 317200 Apr 29 2013 libldap-2.4.so.2.5.6
lrwxrwxrwx. 1 root root 22 Dec 8 09:23 libldap_r-2.4.so.2 ->
libldap_r-2.4.so.2.5.6
-rwxr-xr-x. 1 root root 335264 Apr 29 2013 libldap_r-2.4.so.2.5.6

Ok, there are two copies, retain one and unlink other.

[root(at)localhost lib64]# unlink libldap_r-2.4.so.2
"

I did the above and success:

PATH=/opt/PostgreSQL/9.6/bin:$PATH make USE_PGXS=1 clean all

...

/usr/bin/ld: warning: libssl.so.1.0.0, needed by
/opt/PostgreSQL/9.6/lib/libpq.so, may conflict with libssl.so.10
make -C sql
make[1]: Entering directory `/home/ec2-user/repmgr-3.3.1/sql'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/home/ec2-user/repmgr-3.3.1/sql'

I am going to agree with John's comment upstream that unlinking a file
seems to be dubious. You might want to try linking the file back up
again after you have installed repmgr and see if it causes any issues.
