via some heavy-handed hackery in the ASM symbol handling in case C symbols get a leading underscore (but ASM symbols do not). But this is now like clang and GCC on Darwin work: asm symbols are undecorated, C symbols get a _ prepended, so to connect both some trickery is involved for the ASM symbols that don't have a _ prepended. They must be included in the C symbol table (because that's what we use to lookup also ASM labels), but they also must not disturb the normal C symbol (which don't have the _ prepended), so they need some mangling. A bit unsatisfying, but well. So, add asm-c-connect-test to the working ones for Darwin as well.
