for the following platforms (except resolveClassMethod: and
resolveInstanceMethod:, which are always available):

  * AMD64 (SysV/ELF, Apple/Mach-O, Mach-O, Win64/PE)
  * ARM (EABI/ELF, Apple/Mach-O)
  * ARM64 (ARM64/ELF, Apple/Mach-O)
  * MIPS (O32/ELF, EABI/ELF)

  * PowerPC (SysV/ELF, EABI/ELF, Apple/Mach-O)
  * SPARC (SysV/ELF)
  * SPARC64 (SysV/ELF)
  * x86 (SysV/ELF, Apple/Mach-O, Win32/PE)

Apple/Mach-O means both, the Apple ABI and runtime, while Mach-O means the
ObjFW runtime on Mach-O.
