Most systems don't guard the C reentrant functions but on HP-UX 11
they are not declared
unless _REENTRANT is defined. This causes problems for configure, etc.
The attached change adds the _REENTRANT define when _HPUX_SOURCE is
defined.
A similar change was applied to HP-UX 10 three years ago.
This resolves PR libfortran/63471.
Tested on hppa2.0w-hp-hpux11.11. Committed to trunk.
