llvm: doesn't actually need pythonnative

LLVM doesn't actually need pythonnative, the host Python2 is sufficient but
cmake's executable searching currently isn't reliable in cross-compilations.

Convince cmake by setting PYTHON_EXECUTABLE to point at python2 in the HOSTTOOLS
directory.  Note that currently LLVM *needs* python2 currently:
