lsof: Fix cross 32 -> 64bit ranlib host contamination problem

When building on a 32bit host OS and building 64 bit binaries,
the cross ar and ranlib must be called, or you get an error
as follows:

   x86_64-wrs-linux-gcc    -m64 --sysroot=/opt/build/tmp/sysroots/qemux86-64 -o lsof dfile.o dmnt.o dnode.o dproc.o dsock.o dstore.o arg.o main.o misc.o node.o print.o proc.o store.o usage.o util.o -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -L./lib -llsof
   ./lib/liblsof.a: could not read symbols: Archive has no index; run ranlib to add one
   collect2: error: ld returned 1 exit status
