I'm still certain this is a GCC bug as it bluntly generates invalid
assembler code if the tool chain is build to use emutls as we do in
Genode's tool_chain script. The way I see it noone else tries to use
libgo (or other code that combines 'thread_local' with
'asm("asm_symbol") in combination with emutls.
