stubdom: disable parallel build

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.

....

Disable parallel build for stubdom until the Makefiles are updated to handle
it properly.
