Previously, the compiler would default to hardfloat. This is not supported by some MIPS CPUs. This took me much longer than it should have because of a quirk in the LLVM Mips backend: if the target-features string is not set (like during LTO), the Mips backend picks the first function in the module and uses that. Unfortunately, in the case of TinyGo this first function is `llvm.dbg.value`, which is an LLVM intrinsic and doesn't have the target-features string. I fixed it by adding a `-mllvm -mattr=` flag to the linker.
