Here's how meson does cc.has_function

Since the compiler error comes from the header file with
__attribute__((availability(ios,unavailable)))
The meson check will always pass.
cc.compiles should work though. Is there a reason why it's not used
instead of all the compile_prog checks in ./configure ?
Just because the Meson build system is only a few months old.
Alternatively:
# If we have any includes in the prefix supplied by the user,
assume
# that the user wants us to use the symbol prototype defined in
those
# includes. If not, then try to do the Autoconf-style check with
# a dummy prototype definition of our own.
so adding a "prefix: '#include <stdlib.h>'" to cc.has_function should
work too.
