stubdom: fix parallel build by expanding CROSS_MAKE

Recently I changed my rpm xen.spec file from doing
'make -C tools -j N && make stubdom' to 'make -j N stubdom' because
stubdom depends on tools, so both get built.
The result was the failure below.

....
mkdir -p grub-x86_64

Expanding every occurrence of CROSS_MAKE avoids this error. It also has
the nice side effect of actually enabling parallel build for stubdom.
According to the GNU make documentation $(MAKE) gets its special meaning
only if it appears directly in the recipe:
