Bruno Haible 99b5f472d4 alignalloc: Don't use aligned_alloc if it is buggy. ...

Reported by <gnulib@mifar.in> in
<https://lists.gnu.org/archive/html/bug-gnulib/2026-09/msg00097.html>.

* m4/aligned_alloc.m4 (gl_FUNC_ALIGNED_ALLOC_WORKS): New macro,
extracted from gl_FUNC_ALIGNED_ALLOC.
(gl_FUNC_ALIGNED_ALLOC): Use it.
* m4/alignalloc.m4 (gl_ALIGNALLOC): Invoke gl_FUNC_ALIGNED_ALLOC_WORKS
and define HAVE_WORKING_ALIGNED_ALLOC.
* lib/alignalloc.h (ALIGNALLOC_VIA_ALIGNED_ALLOC): Test
HAVE_WORKING_ALIGNED_ALLOC, instead of testing for an address sanitizer.
* modules/alignalloc (Files): Add m4/aligned_alloc.m4.
