Fix autoreconf step on autoconf >= 1.12

Removing -Wall fixes the following error message:

Enable silent build rules if they are supported

When using reasonably recent versions of automake, the output
of 'make' will now look like:

  CC       c_utils.lo
  CC       walltime_c.lo
  CXX      udgrade_harmonic_cxx.o
  CXX      hpxtest.o
  CXXLD    libhealpix_cxx.la
  CXXLD    alm2map_cxx

etc.

C++ configure script does not require cfitsio's pkgconfig info

It can use pkg-config to locate cfitsio, but the user can also manually
provide CFITSIO_CFLAGS and CFITSIO_LIBS as environment variables when
running configure or command line arguments to configure, as in

  ./configure CFITSIO_CFLAGS="-I/path/to/cfitsio/include"
      CFITSIO_LIBS="-L/path/to/cfitsio/lib -lcfitsio"

A test compile and test link is done whether or not cfitsio is located
with pkg-config.
