Details:

Autoconf's test of `malloc' can fail some times. So it will call a function
called `rpl_malloc' instead. The situation is described described in the
autoconf manual
<https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/Particular-Functions.html>
(under the `AC_FUNC_MALLOC' macro). 

This problem was reported by Alan Lefor and Antonio Diaz Diaz. Since I didn't
have time to implement it immediately, a temporary fix was found by Alan to be
run at configure time and explained in the Known issues
<https://www.gnu.org/software/gnuastro/manual/html_node/Known-issues.html>
section of the manual. In short, if the configure script is run like the
following the problem will go:


./configure ac_cv_func_malloc_0_nonnull=yes


But the better solution is to do what Autoconf has suggested (to actually make
this function available in the library). I find this puzzling however, because
`rpl_malloc' is included in Gnuastro as part of Gnulib (in
`bootstrapped/lib/malloc.c').
