configure.ac: move -pthread CFLAGS setting back where it used to be

The fix for #8276 proposed in #8374 set `CFLAGS="$CFLAGS -pthead"`
earlier than it used to be set, applying it in cases where it should not
have been applied.

This moves the AIX XLC check to a new `case $host in` block inside of
the `if test "$USE_THREADS_POSIX" != "1"` block, where `CFLAGS="$CFLAGS
-pthead"` used to happen.

Fixes #8541
Closes #8542
