Fix binutils build on hppa64-hpux with gcc-16

With gcc-16, implicit function declarations are errors.  We
need to ensure that ffs() and strtoull() are declared.

2025-11-30  John David Anglin  <danglin@gcc.gnu.org>

bfd/ChangeLog:

	* bfdio.c: Include libiberty.h.
	* configure.ac: Check for presence of long long type.  Check
	for strtoull declaration.
	* configure: Regenerate.
	* config.in: Regenerate.
	* strings.h: Include strings.h.

bfd/ChangeLog:

	* configure.ac: Check for presence of long long type.  Check
	for strtoull declaration.
	* configure: Regenerate.
	* config.in: Regenerate.
