[Mimedefang] undefined reference to strlcpy and other sendmail routines on make

[Christopher Biow]

I'm getting the undefined reference, despite the apparent presence of the
strlcpy symbol in /usr/local/lib/libsm.a, as copied from sendmail-8.12.7
tarball install, according to the mimedefang compile directions. "-lsm"
doesn't seem to help, either.

Compiling on Redhat 8.0.
