Details:

The new 3.42 version of CFITSIO can deal with the HTTPS protocol (see its
changes
<https://heasarc.gsfc.nasa.gov/FTP/software/fitsio/c/docs/changes.txt>). But
to do that it needs the libcurl library. If the user has `libcurl' on their
system when CFITSIO is being configured, then CFITSIO will be built by linking
with libcurl. 

Therefore, in the existing version of Gnuastro the `./configure' command will
fail on systems that have `libcurl' because the linker will not find symbols
of the `libcurl' library. 

I am now adding a check at configure time to solve this issue.
