{ This was a hack to support external linking.
All released win64 versions of GNU binutils miss proper prefix handling
when searching for _tls_used and expect two leading underscores.
The issue has been fixed in binutils snapshots, but not released yet.
TODO: This should be removed as soon as next version of binutils (>2.21) is
released and we upgrade to it. }

Using alias allows to support both older and newer binutils.
