File avoid_duplicate_global_symbol_from_asm.patch of Package 0ad.18215

Subject: [PATCH] Use local label in inline asm, avoid symbol duplication

The global label "unsupported" may lead to duplicated symbols
when the function is inlined in multiple places. This may happen
in any case, but using LTO exposes this problem reliably.
