svn commit: r304813 - projects/netbsd-tests-update-12/contrib/netbsd-tests/lib/libc/stdlib

New Revision: 304813
URL: https://svnweb.freebsd.org/changeset/base/304813

Log:
  Don't test `size[i] % align[i] == 0` case on FreeBSD
  
  Per jemalloc(3)/aligned_alloc(3), the behavior is undefined if the size
  isn't an integral multiple of the alignment. Thus, this is a NetBSD-specific
  test.
