LLVM/lldb FTBFS with undefined reference to `__atomic_load_8'

[Sylvestre Ledru <sylvestre@debian.org>]

Hello,

Under both mips & mipsel, lldb (from both llvm-toolchain-3.3 and -3.4)
fails to build from sources with:

/usr/include/c++/4.8/bits/atomic_base.h:496: undefined reference to `__atomic_load_8'

with gcc 4.8

Does it ring a bell? I don't have this issue with other archs.

Thanks
Sylvestre
