As of LLVM 9, this is required for 32-bit PowerPC to properly generate
PLT references. Previously, only BigPIC was supported; now LLVM supports
both BigPIC and SmallPIC, and there is no default value provided.

Could this change affect linking on Windows and macOS (something about symbol visibility)?
Something in a roll-up broke linking libstd in xargo, and most changes look entirely unrelated. I cannot judge this one.

@rust-lang/compiler should we revert and verify?

Turns out the problem was actually caused by a new compiler_builtins release: rust-lang/compiler-builtins#322. Sorry for the noise.
