pathmax: PATH_MAX: use pathconf only when available
* lib/pathmax.h (PATH_MAX): Select the pathconf-using definition
only if HAVE_PATHCONF is defined. Patch by Sylvain Beucler.
* m4/pathmax.m4 (gl_PATHMAX): Check for pathconf.
This avoids a link failure in a PSP cross-compilation environment
described in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/17048
