This vaguely looks like the configure-time check for aligned_alloc
disagrees with what's actually installed in your runtime library. If
your runtime library is older than what you built Emacs with, that might
explain the problem.
What are the values of HAVE_ALIGNED_ALLOC, HYBRID_MALLOC,
HAVE_POSIX_MEMALIGN, SYSTEM_MALLOC, and DOUG_LEA_MALLOC in your
src/config.h file? Do these values correspond to what is actually on
your system?

I see this after make bootstrap, so the configure was run just now.

here are the relevant parts of config.h:
#define HAVE_ALIGNED_ALLOC 1
#define HAVE_DECL_ALIGNED_ALLOC 1
/* #undef HYBRID_MALLOC */
/* #undef HAVE_POSIX_MEMALIGN */
#define SYSTEM_MALLOC 1
/* #undef DOUG_LEA_MALLOC */

how do I find that out?

'configure' says you have aligned_alloc, because it successfully built
an executable that calls aligned_alloc. However, the dynamic linker
fails, in that when temacs runs and calls aligned_alloc, its dynamic
linker fails to find an implementation. Please figure out why that is.
For example, you can compile and run this program with the same flags
you use to compile Emacs:
#include <stdlib.h>
int
main (int argc, char **argv)
{
char *p = aligned_alloc (8, 1);
char *q = aligned_alloc (8, 2);
return p && q && p == q;
}
If it compiles and runs successfully, you can then investigate why it
works but temacs doesn't. Otherwise, you can investigate why it doesn't
work.

So your include files declare alloc_aligned and it links, but it doesn't
run? Sounds like your development environment is messed up.
You might try running the shell command 'xcode-select --install'; this
solved a similar problem when building Ruby, as described in
<https://github.com/rbenv/ruby-build/issues/1133>.
Or you might try configuring with flags that say "build for the macOS
I'm currently running, not for some future version of macOS". Perhaps
something like "-mmacosx-version-min=10.14"? I don't use macOS so I'm
afraid you may have to do some research here.
<https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=15518> may help you
get started.

For what it’s worth, I had the same issue when xcode-select used Xcode 11 beta 5 on Mojave 10.14.6.
$ sudo xcode-select -s /Applications/Xcode.app # (Version 10.3)
and then a new ./configure solved the problem for me.
