Running $(MAKE) like that in a $(shell ) while parsing the Makefile
doesn't work reliably. In some case, make will complain with
"jobserver unavailable: using -j1. Add '+' to parent make rule.".
Also, it isn't possible to distinguish between the output produced by
the target "xenversion" and `make`'s own output.
Instead of running make, this patch "improve" `version.sh` to try to
guess the output of `make xenversion`.
In order to have version.sh works in more scenario, it will use
XEN_EXTRAVERSION and XEN_VENDORVERSION from the environment when
present. As for the cases were those two variables are overridden by a
make command line arguments, we export them when invoking version.sh
via a new $(XEN_FULLVERSION) macro.
That should hopefully get us to having ./version.sh returning the same
value that `make xenversion` would.
This fix GitLab CI's build job "debian-unstable-gcc-arm64".
