.. can no longer be built as an unprivileged user. This worked fine with
version 8.14.8* of both packages.

>How-To-Repeat:
cd pkgsrc/mail/libmilter
make USE_DESTDIR=yes package

cd pkgsrc/mail/sendmail
make USE_DESTDIR=yes package

>Fix:
Setting "PKG_DESTDIR_SUPPORT" to "destdir" in "mail/sendmail/Makefile.common"
would prevent the build failure. But it would still be a regression compared
to the previous version.
