On AIX, avoid a shell pipepline by making makedef.pl sort case insenitively.

Previously the Makefile piped the output of makedef.pl to sort. This had the
side effect of ignoring the exit code from makedef.pl, as make could only
see the exit code of the last command in the pipeline. This concealed the
causes of the parallel make failure when makedef.pl was missing a dependency
on Config.pm
