Revisiting, side effect:
% ident /usr/lib/libarchive.so|awk '{print $3,$2}'|sort -r|head -1
192031 head/lib/libarchive/archive_read_disk_entry_from_file.c

Linking with libarchive now results in:

*** Error code 1

Stop in /home/mel/cvs/utils/tardiff.

% cat BSDmakefile
PROG=tardiff
LDADD=-larchive
WARNS=3
NO_MAN=yes

.include <bsd.prog.mk>

After adding -lmd to LDADD it's trimmed down to:
/usr/lib/libarchive.so: undefined reference to `SHA512_Final'
/usr/lib/libarchive.so: undefined reference to `SHA384_Final'
/usr/lib/libarchive.so: undefined reference to `SHA384_Init'

/usr/lib/libarchive.so: undefined reference to `SHA512_Init'
/usr/lib/libarchive.so: undefined reference to `SHA512_Update'

If this is fixed in a more recent current, then I'll have to provide some 
stubs for these as I'm waiting for the NFS storm to blow over before 
upgrading.

(In case you curious types are wondering what tardiff is, it's something I'm 
writing at the moment, to figure out why 2 tars are different even though 
their TOC is the same and are created from in theory the same source tree).
