The problem looks like this:

  CCLD     ntpd
../compat/.libs/libcompat.a(libcompat_la-arc4random.o): In function
`arc4random':
/br/output/build/openntpd-5.7p4/compat/arc4random.c:183: undefined
reference to `pthread_mutex_lock'
/br/output/build/openntpd-5.7p4/compat/arc4random.c:185: undefined
reference to `pthread_mutex_unlock'
../compat/.libs/libcompat.a(libcompat_la-arc4random.o): In function
`arc4random_buf':
/br/output/build/openntpd-5.7p4/compat/arc4random.c:192: undefined
reference to `pthread_mutex_lock'
/br/output/build/openntpd-5.7p4/compat/arc4random.c:194: undefined
reference to `pthread_mutex_unlock'
/br/output/build/openntpd-5.7p4/compat/arc4random.c:194: undefined
reference to `pthread_mutex_unlock'
collect2: error: ld returned 1 exit status

Adding -pthread to LDFLAGS fixes the problem.
