v86d: Fix cross link using host-cross ar

If building on 32bit host and creating 64bit libraries, the target
package builds should not invoke the 32bit hosts's ar.  Specifically
you will get an error message like:

x86_64-linux-gcc  -m64 --sysroot=/opt/qemux86-64/tmp/sysroots/qemux86-64 -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -Llibs/x86emu v86_x86emu.o v86_mem.o v86_common.o  v86.o -lx86emu -o v86d
libs/x86emu/libx86emu.a: could not read symbols: Archive has no index; run ranlib to add one
collect2: error: ld returned 1 exit status
