Subject: [PATCH] Add --{enable,disable}-maintainer-mode flags

`pip` does not preserve file modification times when unpacking tarballs.
This causes `make` to think that it needs to rerun `automake` when
building `healpix_cxx`. Since only developers generally have `automake`,
this causes the installation to fail.

We need to add

    AM_MAINTAINER_MODE([enable])

to `healpix_cxx`'s `configure.ac` file in order to make `configure`
recognize this option.

Note that this change preserves the default behavior: maintainer mode is
still on by default, as it is if the AM_MAINTAINER_MODE macro is absent.

See <https://github.com/healpy/healpy/pull/156>.
