config,petsc4py: support cross-compilation

On some HPC clusters it is necessary to cross-compile because the build hosts
(login nodes) have a different architecture (or CPU family) from worker ndoes,
for example on ALCF Theta HPC cluster workers are Xeon Phi, so turning on
cpu-family optimizations turns the build into a cross-compilation. The current
./configure fails with SIGILL (Illegal instruction) when it tries to import
`numpy`, which had been cross-compiled and cannot run on the build host.

This patch simply adds (to `./configure` and to `petsc4py`'s `setup.py`) a
means to suppress autodetection operations that involve loading dependencies
for checks and to get meta info like include. Users who cross-compile can use
these arguments to pass the meta info explicitly so that it doesn't need to
be autodetected on the build host.

To interface into `setup.py` an env var is used, because there doesn't seem
to be any better alternative. We don't want to mess with setuptools's
built-in processing of command-line arguments; and extending that seems to
be possible only per command, which is not useful for getting the information
we need at the top-level scope and is also needlessly complicated.
