   Fix arm-softmmu breakage

   Don't use whole-archive for hwlib or libqemu objects

   Signed-off-by: Blue Swirl <address@hidden>

 hwlib definitely needs whole-archive.

No, it works fine without it.

virtio-pci has a constructor and all static functions. It'll be removed from the archive without whole-archive. This is failure that we're seeing.

In general, hwlib will need whole-archive because hwlib will contain things with constructors.

 Why did this break arm-softmmu?  It builds fine for me.

Because fdc.o was forced to be linked in with whole-archive but the
stuff that it depends on may be undefined on ARM. With whole-archive
removed from hwlib, fdc.o is not referenced in anywhere in arm-softmmu
and it will not be pulled in.
fdc.o shouldn't be in hwlib if it depends on stuff not defined in a particular architecture.
