[PATCH] Windows TLS: Section name prefix to ensure correct order.

[David Nadlinger]

  @asl: If I'm not mistaken, what makes .tls unique is that all TLS sections need to be sorted between .tls$AAA (where _tls_start isemitted to) and .tls$ZZZ (where _tls_end is emitted to). For example, on MinGW, the relevant part of the default linker script looks like this:



    .tls BLOCK(__section_alignment__) :
    {
      ___tls_start__ = . ;
      *(.tls$AAA)
      *(.tls)
      *(.tls$)
      *(SORT(.tls$*))
      *(.tls$ZZZ)
      ___tls_end__ = . ;
    }
