strtoimax: Avoid link error on OSF/1 with DTK cc.

* m4/strtoimax.m4 (gl_FUNC_STRTOIMAX): Always test whether strtoimax is
defined as a function.
* modules/strtoimax (Depends-on, configure.ac): Test only whether
strtoimax is defined, not whether it is declared.
(cherry picked from commit ae006b4d5d64c1a5e1ac2b5bd45350d4d3ebb060)
