  could you please review a fix for 7150594?

  This problem is triggered by the fix for CR 7113017. In particular,
  this fix replaces the malloc.h with stddef.h in mlib_types.h. This
  change leads to compiling mlib_sys.c without forward declaration for
  memalign() routine, and cause following warnings:

mlib_sys.c:96: warning: implicit declaration of function 'memalign'
mlib_sys.c:96: warning: cast to pointer from integer of different size

  This cause the problem on systems where size of integer is less than
  size of pointers: the pointer value is clamped, and usage of the
  clamped pointer causes the observed crash.

  As per discussion for jdk8 fix, suggested solution for 7u8 is to roll
  back the original fix for 7113017.
