physmem.c (physmem_total): Use getsysinfo on Tru64 UNIX.

	* physmem.c (physmem_total) [HAVE_GETSYSINFO]: Use getsysinfo on
	Tru64 UNIX.
	(physmem_available) [HAVE_TABLE && HAVE_SYS_TABLE_H]: Use table on
	Tru64 UNIX.

	* configure.in (AC_CHECK_HEADERS): Check for sys/sysinfo.h,
	machine/hal_sysinfo.h, sys/table.h.
	(checkfuncs, AC_CHECKFUNCS): Check for getsysinfo, table.
	* configure, config.in: Regenerate.
