Fix various minor issues with rt-tests build system
The issues fixed are :
* Remove the automatic NUMA detection from the host
architecture. This is broken when doing cross-compilation. One can
still set NUMA=1 if NUMA support is desired.
* Expand the CFLAGS provided through the environment instead of
overriding it.
* Provide a HASPYTHON variable to tell whether the target system has
Python or not. Otherwise, the build system simply tests whether
Python is available on the host. The PYLIB variable is also changed
so that it can be overriden from the environment, in order to
provide the correct Python module location for the target.
