Ok :-)

I don't see archive_cmds being used anywhere for computing link_command.

It happens for example when compiling openldap on linux (after running
`autoreconf -fi'):

/bin/sh ../..//libtool --mode=link cc  -O2 -fmessage-length=0 -Wall     -o 
apitest apitest.o libldap_r.la ../../libraries/liblber/liblber.la 
../../libraries/liblutil/liblutil.a -lsasl2  -lssl -lcrypto  -lcrypt -lresolv  
-pthread
cc -O2 -fmessage-length=0 -Wall -o .libs/apitest apitest.o  
./.libs/libldap_r.so 
/usr/src/packages/BUILD/openldap-2.2.23/libraries/liblber/.libs/liblber.so
