Summary: configure sets HAVE_STRUCT_DIRENT64 when readdir64 unavail

Initial Comment:
After running configure in tcl8.4.5 (and tk8.4.5) I get
a link error
at the end of make because readdir64 is not defined.

I edited the Makefile and tclConfig.sh (tkConfig.sh on
the tk side)
to remove the HAVE_STRUCT_DIRENT64 and was able to
complete the make/install (and run tkdiff as a
testcase)

I'm using linux 2.4.23-rc with libc5.4.44
gcc version egcs-2.91.66.1

Well, I've no idea what to do about this.  (AIUI, the only
reason for having a 'struct dirent64' is for use with
readdir64(), so having one but not the other is perverse.)

apparently dirent64 existence was presuming readdir64
existence, which isn't always correct.  Of course, that is
an ancient compiler setup.
