Comment (by grumpybozo):

 A few maybe relevant data points:

 1. I am having exactly the same problem on a 10.14.6 machine without any
 of the possible issues from running in a VM.
 2. By accident, I discovered that if I run freshclam or clamscan from
 /opt/local/lib/ the warning message is NOT issued.
 3. By running with dtruss, I see a hunt in various directories for
 libclamunrar_iface.so.9 (which doesn't exist anywhere) instead of
 libclamunrar_iface.9.so (which does.)
 4. On a 10.11.6 machine, I don't have this problem.


 The key (I think?) step in the build appears to be this:


 {{{
 libtool: link: /usr/bin/clang++  -o .libs/libclamunrar_iface.9.so -bundle
 ../libclamunrar_iface/.libs/libclamunrar_iface_la-unrar_iface.o
 -L/opt/local/lib ./.libs/libclamunrar.dylib -lcharset  -Os -stdlib=libc++

 libtool: link: (cd ".libs" && rm -f "libclamunrar_iface.so" && ln -s

 libtool: link: ( cd ".libs" && rm -f "libclamunrar_iface.la" && ln -s
 "../libclamunrar_iface.la" "libclamunrar_iface.la" )
 }}}

 There is one small difference on 10.11.6:


 {{{
 libtool: link: /usr/bin/clang++  -o .libs/libclamunrar_iface.9.so -bundle
 ../libclamunrar_iface/.libs/libclamunrar_iface_la-unrar_iface.o
 -L/opt/local/lib -lMacportsLegacySupport ./.libs/libclamunrar.dylib
 -lcharset  -Os -stdlib=libc++ -arch x86_64 -Wl,-M
 -Wl,../libclamunrar_iface/libclamunrar_iface.map
 -Wl,-headerpad_max_install_names -arch x86_64
 ld: warning: ignoring file ../libclamunrar_iface/libclamunrar_iface.map,
 file was built for unsupported file format ( 0x43 0x4C 0x41 0x4D 0x41 0x56

 architecture being linked (x86_64):
 ../libclamunrar_iface/libclamunrar_iface.map
 libtool: link: (cd ".libs" && rm -f "libclamunrar_iface.so" && ln -s
 "libclamunrar_iface.9.so" "libclamunrar_iface.so")
 libtool: link: ( cd ".libs" && rm -f "libclamunrar_iface.la" && ln -s
 "../libclamunrar_iface.la" "libclamunrar_iface.la" )
 }}}

 Note the  '-lMacportsLegacySupport'

 I hope this helps illuminate the problem in some way.
