The logs show that the autoconf test for strtok_r fails in an unexpected way:
checking whether strtok_r works... no
"conftest.c", line 745.2: 1506-766 (S) The universal character name "�" is not
in the allowable range for an identifier.
"conftest.c", line 745.5: 1506-766 (S) The universal character name "�" is not
in the allowable range for an identifier.

"conftest.c", line 745.5: 1506-277 (S) Syntax error: possible missing ';' or
','?
"conftest.c", line 745.2: 1506-045 (S) Undeclared identifier \u00c2\u00a0.
The referenced line in the test program is this:
char *save_ptr = (char *) 0xd0d0;
It looks like a compiler bug to me. I'm committing this tentative workaround:

strtok_r: Avoid triggering bug in AIX 7.1 xlc compiler.
* m4/strtok_r.m4 (gl_FUNC_STRTOK_R): Don't cast an invalid address to
a 'char *'.
