[16/19] Mark ld.so internel mmap functions hidden
Commit Message
Since ld.so internel mmap functions are only used internally in ld.so,
they can be made hidden.
[BZ #19122]
* include/sys/mman.h [IS_IN (rtld)] (__mmap): Add
attribute_hidden.
[IS_IN (rtld)] (__mprotect): Likewise.
[IS_IN (rtld)] (__munmap): Likewise.

For this and all the rest you need to verify that they do not break
anything on Hurd.

For all I know, they are internal to ld.so. Can someone show the
output of
# readelf --dyn-sym --wide elf/ld.so
on i386 Hurd?
Thanks.
