Introduce NO_RTLD_HIDDEN, make hurd use it instead of NO_HIDDEN
On the Hurd, the rtld needs to see its own dumb versions of a few functions
(defined in sysdeps/mach/hurd/dl-sysdep.c) overridden by libc's versions once
loaded. rtld should thus not have hidden attribute for these. To achieve this,
the Hurd port used to just define NO_HIDDEN, which disables it completely. For
now, this changes that to disabling it for all rtld functions, for simplicity.
See Roland's comment on https://sourceware.org/bugzilla/show_bug.cgi?id=15605#c5
The ld.so numbers remain at
8 .rel.plt 000000c8 00000c24 00000c24 00000c24 2**2
CONTENTS, ALLOC, LOAD, READONLY, DATA
9 .plt 000001a0 00000cf0 00000cf0 00000cf0 2**4
CONTENTS, ALLOC, LOAD, READONLY, CODE
10 .plt.got 00000010 00000e90 00000e90 00000e90 2**3
CONTENTS, ALLOC, LOAD, READONLY, CODE
18 .got.plt 00000070 0002d000 0002d000 0002c000 2**2
CONTENTS, ALLOC, LOAD, DATA
which is about 3 times as much as on Linux.
The libc.so numbers get divided by 3 (the remainings are mostly RPC stub calls)
* include/libc-symbols.h [NO_RTLD_HIDDEN] (rtld_hidden_proto,
rtld_hidden_tls_proto, rtld_hidden_def, rtld_hidden_weak,
rtld_hidden_rtld_hidden_ver, data_def, rtld_hidden_data_weak,
rtld_hidden_data_ver): Define to empty.

(NO_RTLD_HIDDEN): Set.
