           Summary: configure adds opensc libs to LDFLAGS when it should use
                    LIBS
           Product: Portable OpenSSH
           Version: -current
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Build system
        AssignedTo: bitbucket at mindrot.org
        ReportedBy: vapier at gentoo.org


configure.ac does this:
                        LIBOPENSC_CFLAGS=`$OPENSC_CONFIG --cflags`
                        LIBOPENSC_LIBS=`$OPENSC_CONFIG --libs`
                        CPPFLAGS="$CPPFLAGS $LIBOPENSC_CFLAGS"
                        LDFLAGS="$LDFLAGS $LIBOPENSC_LIBS"

since we're grabbing libs, we actually want to be sticking that into
LIBS

otherwise, when the binaries get linked, they're of the form:
$(CC) <objects> -o ssh $LDFLAGS <sshlibs> $LIBS

so -lopensc goes into LDFLAGS instead of LIBS and if we use something
like -static or --as-needed in LDFLAGS, the build aborts because the
<sshlibs> use symbols from -lopensc but -lopensc is discarded before
sshlibs get processed
