Khem Raj 1e24d75fea libtorrent: Fix libatomic detection with optimized builds ...

The configure check for -latomic links a program that loads from a
local std::atomic<uint64_t>, which clang folds away at -O2. On riscv32
it therefore reports that libatomic is not needed, and libtorrent.so is
left with undefined __atomic_fetch_add_8, __atomic_fetch_sub_8,
__atomic_load_8 and __atomic_store_8 references and no dependency on
libatomic.

Add a patch that makes the test atomic global and modifies it with
fetch_add() so the check cannot be optimized away.
