There is a difference between libc_hidden_def in .S files and in .c files.
In .S files it will work even if libc_hidden_proto () was not declared
in header files (usually the assembly doesn't even include those headers),
while if you use libc_hidden_{def,weak} without previous libc_hidden_proto,
things will break badly...
