test_build: Update make call
Use ccache and parallel builds by default, unless ${CC} or ${CPUS} is
overridden. Also allow ${WARNERROR} to be set to `no` (it defaults to
`yes` in the Makefile already).
The make command can be overridden by setting ${MAKECMD}. This can be
used in testing environments where GNU make is installed as `gmake`,
for instance.
Run `make clean` ahead to make sure that we always have a clean build.
