Quite similar troubles here on AIX 7.1:

Particular reason here is the _LARGE_FILES macro, defined by config.h, which
has to be defined before any system header.

Same here.

Exactly: Since AIX 6.1, mkdtemp() is declared upon _XOPEN_SOURCE >= 700, and
thus the symbol is available in libc.
The difference is: Upon _ALL_SOURCE (defined in config.h),
AIX 6.1 defines (overrides!) _XOPEN_SOURCE=600, while
AIX 7.1 defines (overrides!) _XOPEN_SOURCE=700,
This particularly isn't a problem on AIX 7.1, but still the check for mkdtemp()
should be extended to if the declaration is available too.
