MIN is used, but param.h may not be included. Define MIN explicitly
because param.h has lots of legacy macro definitions so it should
not be used.

(needed for hjl/pie/static branch)
(will commit this soon)

	* sysdeps/aarch64/dl-machine.h (MIN): Define.

There is only one use of MIN, perhaps expand it there?

Andreas.
