The addresses application got with R_X86_64_TPOFF64 was different than the once libc

R_X86_64_DTPOFF64 testcase is even simpler than that:

#include <stdio.h>
#include <errno.h>
#include <netdb.h>
#undef h_errno
extern __thread int h_errno;
int main() {

R_X86_64_TPOFF64 in application and h_errno relocation via R_X86_64_DTPOFF64 in
libpthread which has its own __h_errno_location() (probably we can kill it later?).
And addresses were different again.

should use symbol_addr instead of sym->st_value.

In glibc, they have #ifdef SHARED magic to either use pthread_functions
table, or weaks. But as we shared object files with both builds, this
does not sounds good either.
The reintroduces the libc weaks.c, but uses them now only with static

provide weaks in forward.c so they end up dereferencing the

nptl: mark symbols with libc forwarder hidden
Add attribute_hidden to all symbols having libc forwarder. This prevents
recursive self calls which would happen if libc is before libpthread in
linking order: the forwarder functions would call itself via the function
table, since the libpthread symbols would get overwritten with libc ones.
This has not been a problem in glibc since there these symbols are marked
hidden with linker version-script. Since we don't use one, we need to mark
these explicitly.
