remove remaining traces of __tls_get_new

Browse Source 
Some declarations of __tls_get_new were left in the code, even
though the definition got removed in

  commit 9d44b6460a
  install dynamic tls synchronously at dlopen, streamline access

this can make the build fail with

  ld: lib/libc.so: hidden symbol `__tls_get_new' isn't defined

when libc.so is linked without --gc-sections, because a .hidden
declaration in asm code creates a reference even if the symbol
is not actually used.
