[Mesa-dev] [PATCH 2/4] targets/xa: limit the amount of exported symbols

[Emil Velikov]

In the presence of LLVM the final library exports every symbol from
the llvm namespace. Resolve this by using a version script (w/o the
version/name tag).

Considering that there are only ~35 symbols, explicitly list them
to minimize the chances of rogue symbols sneaking in.
