I've done some more digging and found that the switch from a gas-derived
as in Xcode 6.4 to the LLVM-based one in Xcode 7 caused this: assembling
the exact same .s file with both assemblers introduces the difference in
relocations causing ld to choke and the 32-bit bootstrap to break.
Command line is
as -arch i386 -force_cpusubtype_ALL -o make-temp-file.o make-temp-file.s
