AIX builds are failing because CONFIG_LDFLAGS is getting set to
-lpthdebug which results in the library being linked before all the
object files.  The library needs to be after the object files and
CONFIG_LDFLAGS is for flags not libraries. This patch basically reverts
a previous one from a few months ago. There might be a better way to do
this but this seems to work OK for me.

	* configure.in: Don't set CONFIG_LDFLAGS to -lpthdebug.
	* config/powerpc/aix432.mh (NAT_CLIBS): Set to -lpthdebug.
