Mark ld.so internal mmap functions hidden in ld.so
Since ld.so internal mmap functions are only used internally in ld.so, they can be made hidden. Don't hide __mmap on Hurd, since __mmap in ld.so will be preempted by the one in libc.so after bootstrap. [BZ #19122] * include/sys/mman.h [IS_IN (rtld)]: Include <dl-mman.h>. * sysdeps/generic/dl-mman.h: New file. * sysdeps/mach/hurd/dl-mman.h: Likewise.
