When a variable HAVE_FOO is initialized to 1 and set to 0 in a different
.m4 file, we have to ensure that the assignment to 1 is done before the
assignment to 0, not afterwards.
Checking the results of
$ grep -n 'HAVE_.*=0' \
$(for f in $(grep -l 'HAVE_.*=0' *.m4) ; do \
if fgrep -l 'DEFAULTS])' $f > /dev/null ; then :; else echo $f;fi; \
done)
I found 4 violations of this rule. This fixes them.

Ensure that HAVE_* variables are set to 1 before they are set to 0.
* m4/fdopendir.m4 (gl_FUNC_FDOPENDIR): Require gl_DIRENT_H_DEFAULTS.
* m4/inet_ntop.m4 (gl_FUNC_INET_NTOP): Require gl_ARPA_INET_H_DEFAULTS.
* m4/inet_pton.m4 (gl_FUNC_INET_PTON): Likewise.
* m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK): Require
gl_SIGNAL_H_DEFAULTS.
