[PATCH 1/2] kvm-unit-tests: invoke $LD explicitly in

[Dan Cross <cross@oxidecomputer.com>]

This change modifies x86/Makefile.common to allow building on
illumos; I have also tested it on Linux.  This switches from
using the C compiler as a linker driver to simply invoking the
linker directly in two places, allowing us to easily use gold
instead of the Solaris linker.
