The build log

/usr/bin/ld: non-dynamic relocations refer to dynamic symbol deny_severity

deny_severity is a symbol defined in sshd.c, but it's there for the
benefit of libwrap. If I'm reading the warning correctly, it's
complaining that libwrap is "non-dynamic".
libwrap is currently built with -fpic. Perhaps it needs to be built with
-fPIC instead? Luk, would it be possible for you to try this out
experimentally and see if it makes a difference?
