Gandalf,

 the simple/short answer is: you can't generate "mips1" binaries
under 6.2. We dropped support for the R3000 and therefore the
minimum mips-level for 6.2 capable systems is "mips2". As this
is so, all of the system binaries (including crt1.o and crtn.o)
are "misp2". Linking with them will make the resulting executable
automatically "mips2".

 There are two ways to generate "mips1" images:

- compile/link under 5.3. This is the official way and will
  guarantee upward compatibility
- try to build a "mipsABI" binary. These are by definition "mips1".
  Certain restrictions apply to what functions/syscalls you are
  allowed to use in such a program. The libraries for linking
  are located in "/usr/lib/abi". You need to install (at least)
  the following subsystems:

  compiler_dev.sw.abi
  dev.sw.abi

Hope this helps
Martin
